Probably nakyums cuteness and sincerity
Not tryna be emotional or anything but i think Seungho just wants love, especially from Nakyum. To answer ur question about what made him catch feelings, it was probably bc how Nakyum was expressing his love for Inhun and Seungho wanted that too. When he was having sex with drunk Nakyum, he was told "i love you" (not directed at him tho) and in the recent chapter he was told that he makes Nakyum feel hot and good. So him feeling love from Nakyum probably made him fall in love. Plus Seungho isn't possessive over any sex partner, he's only possessive over Nakyum.
Yes I agree, i didn't remember that part very well because I've just been continuing reading the new chapters since April so i didn't really remember.But, I agree i mean he most likely never received any affection from anyone.
Thank you for answering
Yeah i just recently re-read it lol
I honestly was thinking that he was catching feelings for real but, in this chapter I started thinking about what made him catch feelings tho x.x the sex?
Like it's usually the "different personality that they never seen before" that makes them fall in love but I'm not seeing this here or anything tbh.
But i guess him wanting to know more about him is a step, he wants to get closer to him. Most likely possessiveness over his sex partner, but it's still something i mean lovers are possessive too. (not saying its love but, something will definitely trigger that emotion soon)
It's a process I'm glad they nobody is just like 'i love you' right away like most yaoi x.x
Let's enjoy the process c:
