Short, cute and pleasant. These are the adjectives I'd choose to define this manga. You get the cute sensei Hana and his cousin(?) Kiichi who are living together. He also happens to be her student and, yeah you guessed it right, they fall in love. But wait! It's just not that! There's more to Koi to Utatane than your average student-teacher romance manga.
Kiichi is a shy kid and Hana is the total opposite of her. She loves to sleep and it seems like she has pretty much mastered the art of sleeping peacefully(Okite Kudasai, Kusakabe-san vibes totally) and helps(and sometimes forces) Kiichi to take a nap and aid him to get a good one at that.
Slowly but surely they start to notice each others feelings and at the end of the manga you get to see the wedding bells tolling. Cute right?
Sadly the manga seems to have been rushed quickly and we don't to get to see much of them in only 28 chapters. Nevertheless, it's cute, totally drama free and will leave you with a happy smile on your face.
I'd have given this a 10/10 but stopped at the 9 just because it felt rushed towards the end. It totally deserves a 10/10.
I got to know about this manga from a reddit post praising Sensei wa Koi wo Oshierarenai. So if the kind redditor is reading this review, thanks a lot for mentioning it!
