It's a slice of life comedy about two couples. They're all friends in one form or another and attend the same school. Some antagonists, some plot relevant drama but genuinely funny, and interesting the further you get into it. The relationship between the couples /friends is interesting. It just takes a bit to get to the main plot as it starts with short pieces. It doesn't vary too much from the short pieces start, but everything eventually begins making sense, I believe. A personal favorite.
Okay and now to answer your request-- it's about a group of 4 male friends in the midst of adolescence.
The story first starts off focused on the "main couple", Jian Yi and Zhang Xixi. Jian Yi is an aloof pretty boy hiding his sexuality and feelings towards Zhang Xi. Zhang Xi is Jian Yi's childhood friend, and although he doesn't show it, he cares about him very much and often gets frustrated at his inability to protect Jian Yi, which I think was a promise he made to him many years ago.
The next couple is about a delinquent boy named Mo Guan Shan (who is rough but kind at heart) and the very popular He Tian. He Tian had a rough upbringing and often times, although he never said it, felt lonely. After Mo Guan Shan causes trouble to his friends, Jian Yi and Zhang Xi, he threatens him to cook for him and be his housekeeper.
Mo, who has no choice due to his abnormal strength and intimidating aura agrees, although reluctantly. He feels a deep hatred towards He Tian, and He Tian is just keeping Mo around to kill time. However, things eventually change and so do the ways they feel about each other.
I don't want to spoil too much but thats basically the two couples.
I heard a lot about 19 days and only good things. But somehow I can‘t bring myself to read it. I read the first 3 chapter already and I tried to read the manga 2 times but I always stop after 3 chapter. Not because I dont like the story but it gets boring for me and idk why. Can someone tell me just a liiiittle bit about the manga? I really want to read it till the end but i‘m not sure about it.
