Some poeple thinks that kind of uke pathetic but I agree with you, I like dongho too..
Its just in these manhwa, ones is the seme who have been hurt so he find himself hard to believe in love again and the other the uke is the one who have been hurt.
So yeah, its not about seme chase the uke, its just about someone who chase their loved ones
Yeah. Ppl these days r totally used to over pampering ukes. Ukes r treated like babies instead of mature adults. And not just Dongho, ukes like Yuuto from Deadlock and the one from Blue Sky Disco and first uke from BJ Alex etc. These should serve to be the motivation for other ukes. I am in a bad mood cause I read a super bullshit list on top 20 ukes. None of the ukes I mentioned above were there. And on the top of that Suha also had his name on the list. I nearly got a heartstokre.
This is a list indicating a bl poll on Twitter

Basically its bullshit

Honestly, am hella tired of semes running after ukes in most yaoi..........
That's why I loved the second uke, Byul's brother, Dongho from BL Motel. The guy was just super above other ukes I have seen. Ukes should not always be on the receiving end while semes be the compromising one. Koisuru Boukun has also given me hella headache with this issue. At this point those comedy scenes no longer seem funny but I feel pity for Morinaga. Can there even be a story where uke go to heights to prove their love for semes? Idk why semes gotta prove every times? Many times I feel like just fucking give up on this damn guy but well not like I can do anything..........
