Marriage of convenience:
Nigeru wa Haji da ga Yaku ni Tatsu (fl works as ml's housekeeper, since it's unconventional for Japanese to have a young housekeeper to live in, they get married)
Shanai Marriage Honey (fl wants to get married after being cheated so she marry a random guy from a dating site but they apparently on the same workplace)
Not married but:
Because This is My First Life (fl live in ml's house as ml needs to pay for his house installment)
Haven't watch it but plan to:
Falling before Fireworks (fl is a rich woman who tired of city life marry a man who live in beautiful remote place)
Want to continue it someday:
You are My Secret (fl and ml is high-school friends or college i forget. Fl want to get married but can't find a match on a big blind date event. Ml proposed fl to get married. But then they work on the same workplace)
Transmigration (just because they're funny)
Mr. Queen (a male chef from the future transmigrated into the past becoming a queen of ml)
Romance between Tiger and Rose (a novelist transmigrated into her novel, marry ml because she force him-fl is a princess from a female-dominated kingdom)
Just read bed scenes, I don't remember bed scenes at least they won't be explicitly shown. But kisses are everywhere. Oh but Shanai Marriage Honey has a few not-explicit bed scenes.
