Great! It's not really applicable in reality because who would pick up a random guy along the road and trust that person to live in your house for months? Lol, not me. Still, as a fictional movie, I liked it. It's comforting to watch. One thing that bothers me is that the male lead left and only wrote "Thank you", then came back like nothing happened. Although he said that it is for him to become a better version of himself or whatever, I am surprised that he really trusted the female lead not to find another romantic partner. He should have mentioned in his letter to wait for him because who knows what will happen in a few months when he's not there? Also! What's wrong with sharing his last name or what he does in life? It's not that big of a deal, just say he ran away to find his own path, that's all. Do not suddenly leave like that without any explanation.

I have so many complaints about him, but anyway, I still liked it overall.
