it's about two friends who are always close outside of school, but the seme is cold to the uke at school. They still always go to school together on a bicycle, and when the seme's friends ask him why they go to school together, he answers that it's because the uke can't do anything by himself.
The uke overhears this and gets upsets, and confronts the seme about it by doing it with it in the nurse's office or something (I think). Afterwards he finds out it's because the seme just didn't want him to be embarrassed if he got too clingy at school (and then stuck to him like glue).
Chapter 2
couple and they've been dating for...2? years. Seme has never been to the ukes house (could also be the other way around) and in the end its revealed that its simply because his bed has a fuck ton of teddy bears and he's embarrassed.
