Winter SangClair is so cuuuute~~~Since Yi Sang keeps forgetting things like his umbrella and gloves, Sinclair frequently shows up to Yi Sang's job (whatever it may be here), and starts to become memorable to the staff.
Yi Sang ends up cautiously explaining that Sinclair's relationship to him is "sort of like he's my wife." Thus, whenever he turns up from then on, the other staff say, "Yi Sang-san, your wife is here to see you~."I'm crying... they're married...Yi Sang-san, you forgot your gloves again, didn't you! It's too cold out for you to be doing that...I apologize... however I am indeed happy that you have come to greet me again in this way....Well, you caught a cold last time, so please be more careful...In my headcanon, SangClair are married, so I'm having them wear rings here.I think a coat in some shade of blue would also suit him well.Welcome back, Yi Sang-san!
