She said, "If you keep giving me things like this, I'll have to prepare a gift for you later. It'll feel like I owe you something!" From childhood to adulthood, this man helped her a lot.

Tristan smiled and said, "It's better if you keep owing me like this. It's best if you can't pay me back." She was speechless. This man! What did he mean!?
