Time travel violates the rules of time, and perhaps some error occurred that caused her to forget that memory until the loop closed, at which point she fully remembered it.

Lu Yan told Zhuang Yan that she loved him very much at the age of 27 because he made her, at the age of 15, feel loved.

She wasn't the type to fall in love at first sight; it was his gentleness and love that made her fall in love with 17-year-old Zhuang Yan at first sight.

The memory of "Serious Smoke" came flooding back like a burst dam. Zhuang Yan had a deep impression of this username because it seemed to be a pair with his username "Solemn Speech". He accepted the friend request because he was attracted by her username.

During junior high, Zhuang Yan was a bit of a chuunibyou (a Japanese term for someone with delusions of grandeur), adding many online friends and sharing his daily life in the "Confessions" section: a song, a short message, a photo...

At 19, he returned to the farm and spent a period of time thinking about how to die. He stopped updating his social media and even changed his profile picture to black.

One night, he couldn't help but post a status update asking, "What should I do if I don't want to live anymore?"

It was on the hospital rooftop that Xia Wan suddenly appeared and said the corresponding line—"If you can't find a reason to live, why not try liking me?"

He accepted the offer and from then on had a reason to live.
