Idk how true this will be but it seems like ML is already hella possessive of MC because of how jealous(?) he got when he realized MC was with his friend. Not sure why and how far back tho. Wondering if it’s like a misinterpretation of his own possessiveness of MC as a brotherly concern or whatever but can’t wait to find out
In the novel, it was in the airport. He described that he didn’t expect him to grew up to be his type, because during his first confession at the playground he only saw him as a little brother since mungmung looks younger than his peers. Then when they were away Sahyeon was pre-occupied with training and work that the confession slowly faded. And mung2 was only a nostalgia. The moment they met he described how attract and different mungmung was as an adult and he was bewitched by his beauty.

Im curious
At what point does the ml becomes interested in the mc and why
