this idea is a bit broad, and i'm totally fine if anyone wants to use it. (pm me tho, i might wanna read it)

this guy is in his teen or young adult phase (can be in high school or college), discovering his gender or ual preference, well... basically he is discovering his identity. so, he couple up and do all those sweet things to this girl, making her totally believe that he loves her and everything. turns out, he's also dating another guy from different high school/college. he tries to justify his action by saying that he's experimenting with himself. like "nothing stays after high school/college..." sorta that thing. then, the author can proceed himself/herself on how to end the story.

OR... you can use scenarios like this: this guy is having a crush on this A girl, but she is very shy or stern (whatever that repels people). A girl is friend with B girl, so he uses B girl to get close to A girl.

OR... when the guy is a very busy guy that he barely spends time with the girl. however, when he needs help, he'll find the girl to ask for help. at some point, this girl will break for sure.

hope it helps :)

Could you tell me a bit of the characters and the general setting? There are many other ways the male lead can use the female OC, but for that it would nice to know what the story will be or is about.

Some examples:

High school au! - He spends time with the female OC to partner up with her for an upcoming project he wants to ace. Knowing that the OC is a good student, he plays her feelings to make her follow his wishes. Or he is a new student who wants to get popular, so he starts to date the popular female OC to gain recognition to have never loved her and only used her in the end. Another idea would be him using her to win a bet. Like date her for xx days/months and make her confess to you.

Rich au! - She is the heir to a whole lot of money and for the male lead to get to it, he needs to marry her. He then divorces her, but gets to have half the share of her money. Or they are only dating while the OC buys him everything. Or the father of the OC is a CEO and ML wants to get promoted, so he dates the daughter OC who always praises the ML to make him get the promotion.

Royal au! - She is a princess that is next in line for the throne. The male lead uses her to get to be king.

Then there are some ideas that can be used generally, like the male lead using the female OC to make another girl jealous. But she doesn't know that until she sees him kissing that other girl right in front of her, or something.
