"Lin Yusen, I am Lai Nai, a sophomore in the English Department. I helped you pick up your student ID card. Should you treat me to a meal? Otherwise, I can treat you to a meal." Lai Nai looked at Lin Yusen's figure walking away and quickly chased after him.
Three years later.
"Lin Yusen, I know you don't like me, but you can't stop me from liking you. You see, you have graduated and don't have a girlfriend yet. We have known each other for three years anyway. I won't disturb you if you are with me." Lai Nai looked at Lin Yusen who was wearing a white coat and said pitifully.
Four years later.
"Lin Yusen, I won't pester you anymore." Lai Nai's eyes shed uncontrollably as he looked at Lin Yusen's back.
Goodbye, Yusen Lin.
