He's the male lead in this story. His whole purpose in life is to be a good boyfriend to the busty downtrodden mc. He won't chest because that goes against his very nature.
Now in real life, you have no guarantee. You can just hope for the best and find someone respectful. The closest thing to a guarantee I'd when the guy has a harmonious relationship with his family, and his parents with him and each other. Sisters help, too.
Ironically while writing this I forgot carrot top was an orphan lol
Irl it could just be lust. Things like falling totally and irrevocably in love don't really happen in real life. Let alone for a guy who has everything with a woman who is considered to be past her prime.
But you aren't supposed to look a gift horse in the mouth. At that point she had nothing else to lose
So what's the guarantee tht this current ML won't turn out to be a trash like mincheol? They are literally following the same steps. Do you not get deja Vu?
