Drama with a not too dramatic secret romance?

Hey everyone! 

Recently I've been craving both low-drama, calm dramas and ones with secret romances in them, such as teacher/student, workplace or  boss/employee relationships. Does anyone know one where both areas intersect? I'm open to all countries of origin, almost all lengths, all settings, sexualities and character ages, but I'd prefer a drama with a calm, almost realistic vibe, like the down-to-earth vibes Japanese dramas often have. If the  leads are too immature with their love interests and bully them a lot, that's a bit of a turn-off.  I especially prefer if there's a significant age difference. 

If that helps, I got this craving after catching up with Cherry Magic, Sapuri and  Nang Ai and finishing movies like Kinkyori Renai and My Teacher. 

Thank you in advance! 

From what I've heard about most of these, they sound like they fit! Something in the Rain and My Rainy Days are on my to watch list and I haven't tried them yet, but it seems like I should. I loved Kinkyori Renai/Close Range Love and Hajimete Koi wo Shita Hi ni Yomu Hanashi, and they're exactly what I'm looking for, so if the others you mentioned are similar, I'll definitely try them. Thank you for the recs!
