Kirin doesn’t find men attractive, KM is the exception. If KM hypothetically dies, Kirin will go back to dating girls. We all know that in real life a hetero guy couldn’t get it up for the same sex so he at least had to have some bi tendencies but again you’re reading a BL with a typical trope in this sense; just let it go and go with the flow.
Yeah, you’re right! Yet, it still annoys me when I see bi-erasure in BL. But I will dismiss that part, see Kirin as “bi for you” and go with the flow - since the rest of the story and art are so good!
Moo is bisexual so you have one in this BL
The author says this in her Ch 60.5 notes. Kirin was heterosexual before he met Kangmoo and the onset of their relationship, but that heterosexual-ship sailed far away since then! He is (at least) bisexual by now. This is just something that bothered me and clashes big time with what I am reading and seeing in the story.
