No romance? That's kinda hard, I watch dramas because of romance ahahah. However I'll try to reccomend you something, hoping it could help you :D
• Overprotected Kahoko (Jdrama) there's a love story, but it isn't the only topic in this drama . It's actually about a girl who was overprotected by his parents all her life, she's now 21 (if I'm not wrong) and slowly starts to explore the world and grow up. It's actually pretty good, a very pure drama, it makes you feel well.
• School 2017 (Kdrama) there is romance, I can't help it ahah, but it's not that cringey lovey dovey you talk about, at least it isn't to me... However it's just a school story, so nothing new, it's about friendship, dreams, bullying. Overall a very nice story, I really liked the leads, they're just a nice match!
• Father is strange (Kdrama) a pretty long drama, 52 episodes, but if you don't watch it now, then when? Actually I'm watching it right now so I don't know about the end but it's pretty good so far... There is romance, I'm sorry ahah, there are a lot of characters and many different stories, not only about love. I think this is a good choice in this period if you're alone, it keeps you up.
