I'll keep this short and simple (if possible). 5-toubun no Hanayome/Gotoubun no Hanayome/The Five Wedded Brides is a very sweet, romantic story thus far about the main protag, Uesugi, and quintuplet sisters who need tutoring in school to pass. Right at the beginning we find out that Uesugi marries one of the 5 sisters, but we don't know who yet which makes it so mysterious and interesting.
The story so far is great! The pacing is perfect in my opinion, and there isn't any filler (so far) to halt the progression of the story/plot. We find out many things about Uesugi and each sister,
and how different they are from one another. We learn how the sisters (somewhat) feel towards Uesugi and what they think of being tutored. (P.s. I love the sisters and seeing them work together at times is cute and amazing!)
I'm really enjoying this series and I really REALLY hope he ends up with Miku! But no matter who Uesugi chooses, I just want an amazing story! I'd recommend giving this a try to see if YOU will enjoy reading it, as not everyone will.
