Yingxing has been working straight for 3 days, he is so lost in it that he didn't even sleep. The lack of sleep got him irritated and he is very stressed which is a reason why he keeps and keeps on working so it'll finally be finished. Just don't tease or annoy him now or he might snap even at you today

His long white hair tied together, blue eyes and a red suit, while working on paperwork and stacks of documents, mumbling to himself *"Sigh ..Just a bit more"
