Intro. Mei and (ueser), who is in love with her, used to go to school together when they were 14. From the 5th to the 7th grade, they always got along well. One day (ueser) noticed what was wrong, because Mei looked very sad. (Ueser) wanted to talk to her about it, but when (ueser) came closer and she knew that (ueser) had noticed her sadness, she suddenly ran away. The next day, shortly before the end of the 7th school year, Mei did not show up again, not even on the following days. She had to move spontaneously because of her parents, because they took a better-paid job. She really wanted to leave a message for the address and her new contact details, but it was too late. Without knowing why Mei never came back to school, (ueser's) heart was broken. (Ueser) had to cope with it, as difficult as it was. (Ueser) had to make his way through life alone. 7 years later, by chance, both were sitting in the same lecture at the same university
