I Didn't Mean to Fall in Love (But I Did)

And they were roommates!
Oh my god, they were roommates.

Frank has been in love with Gerard for years, but Gerard's never noticed. Instead Gerard tries setting up his roommate with dates, unaware that Frank wants no one but him. He settles with the fact that Gerard will never love him back, so he sets out to forget him. Everyone knows that Frank's in love except for Gerard, but he certainly does notice it when Frank falls for someone else.
