The guy is considered a dreamer and stuck to his dreams while with his live in girlfriend. The girl was very patient with him, but patience does not mean you won't explode.

The time she had it with him, and told him to leave, he left and never gave an explanation not apologized to her nor console her. years later he showed up and his friend told her of the reason he left. Personally to me the girl is super loyal to their love that without knowing why the man she loved left after the fight they had still did not move on to find a new love is beyond me. They ended up together so it's a happy ending
