Lily of the valley

Dropped it at episode 3,nothing much to write about it...My mind was having a hard time trying to reconcile the relationship of the main couple.I understand the main lead sees the secondary lead as his pet,needing to be cared and rescued,but seeing him reminiscing about his dog by looking at the picture and the collar i honestly don't understand how the transference of pure love towards a pet will evolve to romantic.Any ways as for the second couple,their storyline seems more interesting and in as much as the NC scene in episode 1 got people off guard,as a person who wears glasses i was just bugged by the guy who was still wearing glasses during the deed.Who wears glasses during intimacy?
