S.Coups:
Seung Cheol would ask you out in an extravagant way, which in his mind, was asking you to come on stage at the end of a concert, and would pop the question then and there. When you say yes, he would tell all the members, who happened to be in on the whole situation, that it was time to perform Adore U. Go big or go home, right?
Vernon/Hansol:
Unlike his confident exterior, Vernon would actually be very shy when around you, even more so when asking you out. He would most likely stay to classic-style dates, like going to the movies and maybe get ice cream afterward. While walking you home he would ask curtly, "will you be my girlfriend?"
Wonwoo:
Unsurprisingly, Wonwoo would take you on a quiet date to a coffee shop and to a bookstore. He said he would buy you any book you wanted! You both browsed and finally, you found a book you were very interested in. Wonwoo and you both made a deal that if you finished your book and traded yours with his, you'd be his girlfriend. Let's just say you read that book in a single night.
Mingyu:
Mingyu would bluntly ask you out at a fan sign, in front of everyone, like S.Coups. He would want everyone to know that you were his and wanted it to be memorable for the two of you. All the members would be in on it, and each member would give you a small gift as you went along the table. Once you reached Mingyu, he would slide you a post-it note with the question "wanna be my girlfriend?" written on it. It felt more like a fan sign for you rather than the fans.
