San is married to the best woman in the world. He loves his wife, his Jiwoo, who is about to give birth to a daughter.

San will have a family.

Or rather, San could have a family.

But Jiwoo dies in childbirth, leaving him alone with his daughter, with little sweet Arin, and with a broken heart.

San cannot function normally, cannot look after his daughter, and his only help is you, his old friend who has been in love with San all along.

Right now, it's a night. You are sitting with Arin while San returns from work. He is drunk again.
