As a housewife, Yamada Masayo has free time after sending her husband and children away in the morning.

When Tang Ze and the other man arrived, the three of them quickly set off for the stairs where they witnessed Miss Guangzi being pushed down.

"This is it."

Yamada Masayo led the two to a staircase and said, "I heard the screams and rushed here, only to find Miss Hiroko lying on the ground."

"What's the exact time?" Tang Ze asked.

"It should have happened after 7 o'clock last Wednesday evening." Yamada Masayo said after thinking for a while.

"Is that so?" Tang Ze nodded, and then called on Nanatsuki Koshimizu to start searching the steps to see if they could find anything.

The steps here were generally clean, so Tang Ze walked down the stairs and finally only found a nut in the corner of the stairs.

The surface of this nut is painted green and seems to have no connection with the case.

There is no gain other than this.

"Let's go to Miss Guangzi's house." Tang Ze suggested.

"Okay, after all, there really are no clues here." Koshimizu Nanatsuki nodded in agreement.

"Then I'd like to trouble Mrs. Yadai to help lead the way." Tang Ze looked at her and said with a smile.

"I can take you there, but..."

At this point, Yamada Masayo said a little embarrassedly: "Can I not go in with you?

After all, Miss Guangzizi's home is near ours. If they knew I asked you to investigate, I would definitely be ostracized."

"I understand, Masayo. Otherwise, you just need to lead us to the apartment manager."

Tang Ze smiled and said, "When the time comes, we will identify ourselves and ask them to help open the door."

"I understand. Sorry, it was us who entrusted you with the task." Upon hearing this, Yamada Masayo bowed to the two of them and said embarrassedly.

"It's okay, Mrs. Masayo, you're doing this for the children." Tang Ze smiled and expressed his understanding of the other party. After all, if Yamada Masayo went to Miss Hiroko's house with them, the other three people would definitely think that Yamada Masayo was meddling and would stop their children from interacting with the other children.

Therefore, the harmony that their small group needs, even if it is only superficial harmony, must be maintained by their common advancement and retreat.

Everything is for the children, this is what is called a mother friend.
