Bl manga, the most memorable i could remember is that on the 1st chapter was seme got dumped by a girl then at the same time the uke confessed, the only thing the seme agreed is that he set a boundary to the uke to not become too overbearing in the relationship, the seme regretted it afterwards cause he started to fall in love instead (not knowing/denying it).
Uke accidentally encountered the seme kissing a girl (unintentionally) and was nonchalent about it, the seme was interested to the uke afterwards cause the uke did not start questioning him
The author really abandoned karyan ToT
