trying to find this specific manga i read and losing my mind. they were neighbors in the same apt building. ml was younger than fl, in college i think? he was a model but she didn't rlly know. she scolded him often + was wary about their age difference but loses it/goes subby every time he takes his shirt off/shows him her pecs. LMAO it was kind of ridiculous but i need to find it for peace of mind

okay maybe it's not here anymore but there was this webtoon where the main character meets someone super important to his job like he's pretty high ranking and the mc discovers that the super important guy used sex to get where he is. he was like a CEO or something. does anyone know this webtoon and the title of it? thanks
