I found this manhwa where the ML confesses to his best friend, the MC and now idk where it is. I know it's been translated here.
I specifically remember the cover being the two of them. The mc has light brown almost orange hair and he's wearing a beanie while the ml has black hair.
The scene happened in the first two chapters and it was around winter if I'm correct. I'm sorry for being so vague don't remember much about it.
