When someone you care about rejects you, it can be tough to handle. For some, the pain might lead them to seek comfort, or attention from others as a way of coping. Even though it's not the best choice, it also happens irl, not just here in fiction/bls. It's like they're trying to find validation and affection from someone else when they can't get it from the person who turned them away. Basically it’s a messed-up way of dealing with the pain and confusion.
Ps: ik this is super random HAHSHAHAH i just thought i’d be okay to answer.
me personally if someone i loved rejected me i would just start whoring myself out 100%
I will never understand why people think it's a good idea to go and sleep around with randos in a self sabotaging way because you got rejected, what the fuck is the point? but i guess it's the classic way for yaoi and bl to create angst, which I find hella weird. This trope is so overused.
Also, how come the uncle never helped Asa even after knowing everything he was going through? What an incompetent guardian.
