I read a webtoon, caught up and then forgot the name of it.

The MC is a dude who, at the beginning, tries throwing himself off a bridge but gets interrupted by a car crash. The driver is underage and borrowed his elder brothers gift to him early. Not sure how but the brother convinces MC to concoct a story about the crash to keep from getting in trouble. I think the MC was getting paid for it. Anyway, the MC meets the ML, whom he gets into a casual (on his end) relationship. Literally everyone else knows ML. Likes him but MC has depression so he's constantly putting himself down. He ends up getting pregnant at some point and ML tries to take care of him despite the dude himself being unaware. MC is very self destructive and tries to leave when he thinks ML plans on getting married because he got 'someone' preggers.

Sounds like Bye Bye by Sorim and Kang Pu Con.
