In a drama slump

I was in a slump sometime in August but it stopped after I went on a thriller/crime marathon but I think that's why I'm in another drama slump. I guess I got a little bored with that genre aft watching it non stop. I hope someone can recommend a drama that can stop my drama slump, any genre is fine as long as its not crime/thriller. Also if possible a romance drama without love-triangles or very complicated plot. Sorry if I'm too picky and thanks in advance :)

I recommend you to try Because this Is My First life  and Reply 1988 (there is a love triangle here but it’s not the main plot like in Reply 1997) 

Romance:

+1 Marriage not dating

+1 Tatta Hitotsu no Koi

• We married as a job
• Kahogo no Kahoko
• It's not that I can't marry but I dont' want to
• Boku, Unmei Hito desu
• Soratobu Kouhoushitsu
• Live up to your name
• The Greatest Love (there's a love triangle but it does not bothers you)

Other genre (no suspense/action/thriller):

• Rookies
• Tumbling
• Aogeba Toutoshi
