Do I Have To Dig My Heart Out For You To See It?

Who was she socializing with at night?

He actually did not care about her day, what she encountered, or who she was with. He just waited for her every night, probably to fulfill his responsibility as a man.

In that relationship, he had to bear the responsibility because he felt that he owed her one. In fact, there was no such thing as owing anyone anything. 

Back then, she had risked her life for him. The more she thought about it, the more she felt that it was because she had depression and did not want to live anymore.

Before she died, she wanted to repay him for saving her life, and they were considered even.

At that time, she really did not have much feelings for him. If Finn had not suddenly said to start over, she might have told him the real reason long ago.
