Ichinomiya Kou has always lived according to the creed of his wealthy, successful family: never be in debt to anyone. But one day, under the Arakawa Bridge, his life is saved by a homeless girl named Nino. In order to pay her back, Kou promises to be her boyfriend; and thus begins his new life under the bridge.
This is a bit of an older show but holds up well in 2022.
So this show is absolutely ridiculous. Don't even try to make sense of some of the lunacy in this show.
That said it is absolutely hilarious. Some of the jokes had me in stitches laughing.
So the shows premise is even ridiculous. The main characters family has a tradition to under no circumstances be in debt. The lengths they go through just to maintain that is crazy. Unfortunately Kou, the main, ends up having his life being saved by Nino a homeless girl. As repayment for the debt of saving him she asks for him to fall in love with her. Stuck to his never having a debt he dedicates all of his being into her request. With that she expects him to also live in the riverside homeless.
Don't put too much thought into this one. just enjoy it for what it is an absolutely bonkers comedy.
There is also a season 2/Sequel which I am yet to see.
