I absolutely haaaate how the MC only confessed/hit on to the ML after seeing his crush with her gf(?) I was really in it for the slow burn but immediately when he realized his crush was out of the question he was like "meh anyone who likes me will do," I get he had moments where he was strangely fixated on the ML, thinking of him regularly, and even jacked off to him but honestly nothing gave any sign that he was truly romantically interested in him... But, oh well, I love the art style, comedy, and characters to this
