Okay, so~ I just came back from reading till chap 56 of the novel and literally everyone KNOWS the seme wants to f*CK the uke except the uke himself LOLOLOLOL it's pretty fun how some of the characters are pretty direct about this.
Mine spoiler:
Seme tells he wants to date the uke pretty fast (this surprised me cause I thought it would take them more time). The way their relationship develops is kinda refreshing, but honestly the swimming plot isn't my cup of tea so... Meh~
