Business Kon: Suki ni Nattara Rikonshimasu (2024)

Having the same marriage for convenience plot and both are Japanese dramas.
The female leads are both cute and kinda shy.

Yuki Rio, the daughter of an old, prestigious family in Kyoto with over 1,000 years of history, enters into an arranged marriage at the age of 16 with a man she’s never met. Her husband is Takamine Masatomo, a handsome CEO in the IT industry. Every year on her birthday, she would receive 50 million yen, making their relationship one based solely on money. One day, after ten years had passed with no contact, Rio decided to move to Tokyo. She asks her husband, whom she’s meeting for the first time, for a divorce. On the other hand, Takamine finds himself unexpectedly attracted to Rio and doesn’t want a divorce. Thus begins a romantic battle between a wife who wants a divorce and a husband who refuses to let her go.

Contract marriage without love but pretty mutch from the start the ML is teasing the FL and causes situations which (romantocally) irritate her.

The character of the FL in both the series felt similar. Even though one starts with relationship and the other as a business wedding contract, both gave me similar vibes.

The same premise of having arranged marriage.
Arrange marriage that gains benefit to both parties, usually reason behind is the house.
