The two attend the same university and have become a campus couple.
I saw a post on Twitter about a stethoscope during a fansign for HamEol, and the idea flashed through my mind. They started dating after meeting by chance at a school retreat, exchanging numbers, and drinking together. They ran into each other at school two days later and became very close. They went out for drinks just the two of them, got wasted, did 'that'... and started dating!!
After Sungjin returns from school, Dowoon takes a stethoscope out of Sungjin's bag and is playing with it.
He puts the stethoscope in his ears and listens to his own heartbeat.
Thump, thump, thump, thump
Sungjin comes out after showering and finds Dowoon playing with his stethoscope.
