Found this one on Viki. It's a short 6 episode Jdrama. I'm 3 episodes in and I love it! It's adorable!
Synopsis from mydramalist: Hiro's so stressed out at work that he can barely have a proper meal or get some well earned sleep. When he passes out on the sidewalk after yet another stressful day, an unfamiliar face calls out to him. Apparently, they once promised to mary each other? What's Kai Fukaya's deal, and why is he so insistent on assuming the role of Hiro's fiancé?
I'll probably end up finishing this one tonight. I've no plans to do anything today because I spent last night cleaning out my closet and bedroom which was pretty dusty and today my nose is stuffed and I feel like I have a cold. Can't stop sneezing and nose is runny. I know better than to clean a dusty area with a mask on but last night I didn't wear one so now I'm suck with a stuffed nose and lots of sneezing. I'll be fine by tomorrow morning ofc, for when I have to go back to work!
