Sand Castle (kinda bc in the beginnig the ml is a jerk and the mc is a doormat but he is contantly being called out for his tendency to fall for mean guys and his "i can fix him" mindset, later when mc has had enough, ml does the chasing/yearning while mc basically loses his feelings and see him as pathetic)
this one since guilty as sin song wise especially fits the two of them relationship wise a little too well

it’s ongoing at 78 current chapters with a very pale light yellow flag to start mc who’s genuinely harmless besides being a narcissist playboy who’s also a extremely loveable relatable dumbass
yes, mc does ‘absolutely’ fall hard first despite the at first usual denial alongside other things and while having a big ego he becomes subtly softer throughout the story to ml while not having his own personality taken away thank god
I don’t want to spoil the plot since it’s really genuinely good despite being smut heavy
the 8 episode anime adaptation from last year is optional to watch if you’re already reading the manga since it just leads up to chapter 24 with minor changes
but man they did not hold back in the uncensored version of the anime with the sex scenes, my god
it also got a drama adaptation of 10 episodes in april if you’re into drama’s

GIVE ME TOPS WHO YEARNNNN AND THEIR BOTTOMS JUST DONT GIVE A FUCK PLEASEEEEEE
