Ikenai Futari

Regret! Love that hasn't started yet! A room sharing romantic comedy!

When they were young, a man and a woman who were childhood friends who promised to get married if they were single even at the age of 30. And so the two of them, who turned 29, had no choice but to start living together.
They argued over which fabric softener to use, and how many eggs to buy... Even if there is love, it is difficult to live together. Not to mention how difficult it is when there is no love...!
