please help me figure out the title of this manhwa!

I'm not sure if its high school or uni based but there's a scene where they're on a trip and everyone drinks; MC and ML are in different rooms. MC's friends decide to leave him and ML comes into the room to clean up and spots MC sitting outside sleeping/listening to music. At some point, I think they share a kiss and MC later forgets about it. I think they both secretly took pictures of each other on the pier as well unless I'm mixing a different manhwa plot (if that's the case, would love the title of this too!) 😅
