Actually Nan Shen himself had planned to go have his lunch leaving Tan Hua behind to finish her work but when he saw how Tan Hua was 'diligently' doing her punishment with that gloomy face, he felt...guilty.
Why the hell he felt guilty?? 😩
He just suddenly felt guilty if he leave Tan Hua alone and went having his precious lunch time. He felt like...this would surely made Tan Hua felt lonely...
So in some kind of sudden impulse, he decided to remain here until Tan Hua finished her work only then he would ask Tan Hua to buy him a meal.
But now...he felt like he had made a wrong choice!! Lonely your ass! Look at that boy was he going to feel lonely if he left him alone?! He bet that boy wouldn't feel so.
He forgot that this boy in front of him actually wanted to leave his sight for every single second. He should knew that the moment it was just the two of them alone...they became awkward...for no reason!
