Hiroshi Kato said, "You can say whatever you want to say!"

Guan Feng cut to the chase: "Where were you last night? What were you doing?"

Hiroshi Kato said, "I was in the apartment last night! How could I remember doing something from so long ago?"

Guan Feng frowned and asked, "Really? Last night's events were so long ago? Do you think this answer will convince us? Kato Hiroshi, I need to remind you that although there are no security cameras at the apartment entrance, there are cameras at all four main entrances and exits. If we check them one by one, do you think we'll find anything?"

Upon hearing this, Hiroshi Kato's expression darkened, and he exclaimed, "You are violating my privacy!"

Guan Feng said calmly, "Privacy? Now that this involves a murder case, you live next door to the victim and are her good friend. Is our routine investigation considered privacy? If you can't even remember something that happened overnight, any police officer would be suspicious!"

Hiroshi Kato shook his head and explained, "That's because I drank last night! So I fell asleep and don't remember any of this!"

Guan Feng stared at Kato Hiroshi and reminded him, "See! Don't you still remember?"

Hiroshi Kato said, "..."

Guan Feng asked, "So you mean you fell asleep after you came back?"

Hiroshi Kato nodded and said, "Yes."

Guan Feng then asked, "Around what time do you rest?"

Without hesitation, Hiroshi Kato replied, "I don't remember the exact time, but I went to sleep as soon as I got back last night."

Guan Feng, observing the other person's attitude, asked, "Did you come back alone, or with Nishimura Yoshiko?"

Hiroshi Kato said, "We came back together."

Guan Feng then asked, "So that's around 8 o'clock, right?"

Hiroshi Kato shook his head and said, "I really don't remember the exact time. I drank quite a bit of alcohol at the time, and the osmanthus flowers on campus were in bloom, so I felt a little uncomfortable breathing and thought I would go back to my apartment to rest. I really don't remember any of the things you're talking about!"

Guan Feng frowned and said, "Do you have symptoms of pollen allergy?"

Hiroshi Kato nodded seriously and said, "Yes, I really don't know why there are so many osmanthus trees on your campus."

Guan Feng said casually, "Isn't it normal for schools to plant flowers, trees, and shrubs? It's a reflection of a beautiful environment. I remember that the campus of Southeast University was full of cherry blossoms, which was praised as a beautiful sight and attracted many tourists. Why can't we plant osmanthus trees in Hua'an?"

Hiroshi Kato shook his head and said, "That's not what I meant! I just have a pollen allergy, and it makes me feel really uncomfortable when I smell these."

Guan Feng asked, "Is your pollen allergy severe? Do you need medication?"

Hiroshi Kato shook his head and said, "It's not too serious! But I always keep some medications in my room."

Guan Feng asked, "Would it be convenient for us to take a look?"

Hiroshi Kato went back to his bedroom and took out a bottle of spray.

Guan Feng looked over and saw the same thing as what he had seen in the trash can.

He frowned and looked at Kato Hiroshi, asking, "I see this bottle isn't opened yet? Normally, these kinds of sprays are opened so they can be used anytime, right?"

Hiroshi Kato said, "I just finished the old bottle, and this is a new one that I haven't had a chance to open yet."

Guan Feng sensed something was wrong and continued, "Did you know that Nishimura Yoshiko also has this problem?"

Upon hearing this, Hiroshi Kato said somewhat dejectedly, "Yes! Her condition is much more serious than mine. She even feels unwell when she inhales pollen, so she always carries this medication with her. In fact, she was the one who recommended this spray to me."

Guan Feng asked, "Did you hear anything unusual last night? Like, Miko Nishimura coughing violently because she inhaled pollen?"

Hiroshi Kato shook his head and said, "No! I drank quite a lot last night. You know, when people drink, they get dizzy and lightheaded. I don't remember anything after I got back."

Guan Feng said, "Mr. Kato, I need to remind you of something: Nishimura Yoshiko's window was pried open last night."

"What?"

Kato Hiroshi asked, somewhat surprised, "You mean... a thief?"

Guan Feng nodded and said, "We have found the thief. He has confessed that he climbed in through the window and then committed the theft."

Kato Hiroshi shouted hoarsely, "It must be him! He must have killed Nishimura Yoshiko! Yoshiko's window couldn't be opened; it would make her feel sick. Did he open the window? Did he? He deserves to die!"

Guan Feng reminded him, "Kato Hiroshi, I suggest you calm down! Although the window was opened by a thief, he didn't kill the person."

"What's the meaning?"

Kato Hiroshi looked at Guan Feng with some confusion.

Guan Feng observed Kato Hiroshi's subtle expression and slowly said, "It's simple! The thief only opened Pandora's box. Even if the window was opened, the concentration wouldn't be enough to kill. The real culprit is someone else!"

Kato Hiroshi's tone was one of shock: "How is this possible? Who could it be? Miko is such a good person, how could someone want to harm her? I will never let them get away with this!"

Guan Feng shook his head and said, "We are still investigating who it is, but Professor Kato, think about it. If it really is pollen allergy, wouldn't people outside hear a violent coughing sound with the window open?"

Hiroshi Kato nodded and offered his own reasoning: "Could it be that Miko closed the window herself again?"

Guan Feng asked, "You mean... she noticed the window was open, was afraid pollen would rush in, and then subconsciously closed it, causing her cough to go unnoticed?"

Hiroshi Kato nodded with a very serious expression.

Guan Feng shook his head and said, "Do you think that's possible? What about the medication she had? The spray to relieve pollen allergies, do you think she wouldn't have it?"

Kato Hiroshi said somewhat dejectedly, "She gave me a bottle yesterday, what if it's all gone?"

Guan Feng: "???"

He looked at Kato Hiroshi and asked, "You said she gave you a bottle yesterday?"

Hiroshi Kato nodded and said, "Yes, she gave me a bottle when I came back last night."

Guan Feng asked, "Did you go into her room then?"

Hiroshi Kato said, "Yes, I was waiting in the living room! But I thought she should have some spares, since her pollen allergy is much more severe than mine. If I had known she didn't have any medicine, I would never have accepted it."

Guan Feng said, "Is this your judgment, or what you actually saw?"

Hiroshi Kato said, "I'm just making a judgment, since her medication was in the bedroom."
