Help!

I was reading this manga, but I lost the tab and I don’t remember the name! T^T
It’s a college setting where the blonde character is a TA and does lab work. He’s socially awkward and doesn’t talk to anyone but secretly he’s a a total weirdo at home. He roommates with a dark haired character that has a thing for him which is why he offered him to move into his one bedroom. The dark haired guy confessed to the blonde but the blonde hasn’t realized his feelings for him so he’s using him to get away from home. Does anyone know the title?? Plzzz （/TДT)/
