So... it's because she made him feel a bit upset that he tried to bully her. Then he helped her when she was in a pinch and made her do an all-nighter report.
I kind of view this in a positive way, minus the first one. I'll be thankful to be saved in this kind of situation where I'm feeling somersaults of shame and disappointments (he didn't wait, he has a girl with him and he didn't apologize for not being able to send a message. Oh and the sister part too.). I'll be glad to do the all-nighter report so that I can forget what happened. Seriously, 'cause if not, I'll be beating my poor pillow or have a drink that won't help me with work the next day (which is not for her since she likes her work etiquette).
Thank you for the chapter!😊
