pls help me find this bl manhwa?!!!!!

Okay so this is the plot also I don’t remember much but it has multiple season with each season having different characters and plot drawn in different colors. Like one season would have 20 ch and all the art was just one color like yellow. Most of the seasons centered around college students in Korea. I remember one season was like blue and another was orange or smth. In the 3rd or 2nd season all the characters has yellow like it was just yellow black or white. In that season it was abt a top and a bottom that had a one night stand and the bottom couldn’t recognize the top after meeting the top again cuz of his glasses.
