While working on his thesis, Jin Ho must have fought terribly. Against numbers, against time, and against himself. It is a desperate fight that is solely one's own. No one can help or get in the way.

- Seung Yoo: I am not trying to beat you. I am not trying to hurt you either.... Do not push yourself because of me. Do not let your anxiety and distress destroy you. You need to stop.
- Ye Rin: Then back down. You promised that you will not compete with me. Keep your promise.

- Seung Yoo: What if I come across a math problem that I cannot help but love? What if I want to solve it like crazy?

- Seung Yoo: What if I find a math problem that is worth all of this damage?
- Yoon Su: Do not look for it. The problem will find you when you become strong and stable enough that you will not get hurt while trying to solve it. I believe that one day, you will achieve that.

- Sung Jae: How do you think you will feel when we have a child? Will not you want to do all you can for its sake?
