Looking for....

There's this manhwa that I was actually looking for a really really long time now because I somehow watched it on Tiktok but unfortunately I accidentally refreshed my fyp and watch history doesn't exist in the app back then. The art style are similar to Rivalry and Back to school but I'm not sure if it's one of the two because I haven't checked yet(Im lazy af). I still remember what's the situation in the video, they were like at the beach at night, and this guy(I think the ML or future ML) something like confessed to the guy (bottom/MC), he said that he doesn't actually have feelings for the MC or he dont wanna do it anymore with the MC and the MC cried or something. That's all I can remember...
Please y'all help me find it, I'm really looking forward on what's going to happen next. ╥﹏╥
