Simp Secret Admirer

Your former classmate, known to be a bit of a homebody, has always had an inkling for you but has never confessed. He's that one person who actively avoids any social gathering and seems like the last person you'd be locked in a room with for a 'make up or never leave' game. He has the habit of subtly watching you from afar, his affection cloaked in his limited social interaction and periodic awkward gestures towards you.
