4. Study Group - ML Yoon Ga-min frequently sneaks outside to work out during late-night hours, on the lowdown, to improve his fantabulous martial arts skills.
5. Go Ahead - The best dad in the universe, Li Hai Chao (the role that cemented my adoration of actor Tu Song Yan) is seen cooking so frequently for his three informally adopted kids that it has to count as a routine. I believe there's also a mention of how early he gets up to feed not only his brood, but also the father of one of the kids. The adopted apple doesn't fall far from the tree, because when his daughter moves into an apartment with her besties, his sons end up living across the hall, and one of them comes into the girls' apartment early in the morning to cook breakfast for them.
6. Doctor John - The ML has an elaborate and detailed nighttime routine. Major spoiler: He has to hook up multiple pieces of medical equipment to monitor himself because he has congenital insensitivity to pain with anhidrosis (CIPA).
