At the beginning of this manga I felt the same but you surely can feel how sincere Yechan's feeling are. In real life if a person like him approach me I'd be mad at the beginning but I think I can accept him later, maybe a person kind like him is capable to open me up? I don't know cause I don't know nobody like this but I really can't hate him, he is such a cutie I need him in my life T.T
well you can open up to someone and still have a need for your own space. ive had people like yechan in my life before and they really sucked the energy out of me even though they were nice, their sincerity of their feelings didnt change that. these bubbly extroverts can make an introverts life better but they can be an introverts worst nightmare if they dont respect your boundaries
i get why yechan is so clingy but as an introvert who needs lots of personal space reading the chapter feels painful i respect sunyool for being so patient bc i wouldve gone mad already if i was him
