Help

I forgot the name of a BL manhwa I read. It’s a 3p story where the main character is the top, (1 top x 2 bottom). I think he had dark hair. The top is smaller than the two bottoms. One bottom has light hair and is flirty, the other has a colder and intimidating personality. The two bottoms are in a relationship and the flirty one was the one to make a move on the top first. The flirty one wants to bring the top into the relationship and have him be like their dildo lmao. The top was a virgin and wanted to be in a relationship. This all happens in a college setting.
