Idk if this fits your preference but it mostly fluff and the drama isnt too intense but I love the dynamic of the MC and ML
1. 40 Made ni Shitai 10 no Koto (co worker)
2. Tameshi ni Komando Itte mita (friend to lover)
3. Pride ni Kiss (co worker)
4. Susumu X Minoru (friend to lover)
5. Spinach Bouquet (enemy to friend to lover)
6. 18.44- (childhood friend to lover)
