Shin went back to their house completely exhausted as he really couldn't understand his seniors from the research department. After the 'introduction' earlier, all of them asked Shin to have a quick match against each of them as a form of welcome party for him who just joined their department.
The tone that they were using when asking him was quite polite, making him think that he could refuse their invitation. But when he showed some sign of refusing them, those seniors suddenly put up a creepy smile that seemed to be warning him to reconsider his decision.
Helpless, he could only nod his head and agree to them and had a quick sparring match with each member of the research department. But he would surely not let himself get bullied one-sidedly and put up a good fight. Though, it only lasted until his seniors took him seriously.
