Mingwa always pays such good details. For example: the gift Kim Dan gave to Jaekyung is a real thing, it's a DIABOLO DE CARTIER SEAL KEY RING. The name means Devil however the key ring is from Cartier's "Freed Bird" collection which shows the complexity of Jaekyungs and Kim Dan's relationship. Jaekyung is likened to the devil, he shows no real emotions and care for others and Jaekyung rejecting Kim Dan's key ring could symbolise him keeping Kim Dan "locked up"
