Yeah honestly… there have been people speculating that the guy ML is mentioning doesn’t even exist, that is the MC that changed his name, but he can’t remember
I feel like whether Mc is or is not the guy he's looking for it's all about respect and seeing the person Infront of you
Though in the last chapter you can see his vulnerability (allowing ML to see into the life he has lived), after years alone, after being forgotten, there's someone by his side that even though they don't see /him/...they are still there. I think the reason he allows and tolerates ML's tantrums and feelings, is because he may crave having someone in his life, that cares about him (even though ML doesn't really care about /him/). Is weird ╥﹏╥
Right and I think mc can understand ml feelings of grief, in a way he probably knows that ml is going to have to let go of Seoho , mc himself doesn't even believe Seoho is alive but reincarnated, he probably can't bring himself to dislike ml just find him annoying lol. I love how strong yet sensitive Minchan is hes such a well written character.
I feel for the mc so much that I start to get frustrated with the ml. Being constantly referred or called a different name must make you feel so invisible like you don't exist.
