help me find this BL please

please help me find this BL based off this really bad and super vague description of the only part that i remember...
all i remember is at some point in the story the mc has to dress up as a girl to help some girls at his college with a dance performance or something like that, and then after that they all go out to eat/drink and then some other side characters (both male and female) start sexually harassing him and like making him uncomfortable by commenting on how he looks, im pretty sure at some point someone tries to stick some dollar bills into the strap of his shirt or something like that, and then like the last thing that i remember is that the MC's BF notices that he's been really off and distant lately. im pretty sure the mc had black hair and I'm like 90% sure it was a college setting
