Sensei Kunshu is made by the same person who made Heroine Shikkaku, it carries on its exciting art style and unique characters. Ayu is a girl who has never had her feelings returned by a guy before, in fact at the beginning of the manga we see her being rejected. Ayu is a clumsy girl she doesn't have enough money to pay for the food she was eating out of despair of being rejected and thats when she meets Hiromitsu.
Hiromitsu is a blunt guy he tells things to Ayu straight up. They have completely different personalities and thats what causes them to balance each
other out. Sensei is a calm guy while Ayu is loud. Sensei is probably the only person on Earth who'd be able to stand Ayu. Sensei is also very closed about his feelings at first, he kinda toys with them but you can see him slowly opening up and deeply caring for Ayu.
Momoko sensei has an interesting art style and kits often shown in this manga... its very livid and thats what I love about it. It brings out Ayu's personality and it fits her. The art is beautiful and you can see the resemblance in Heroine Shikkaku.
The characters are unique and you'll most likely never find a protagonist like Ayu anywhere else. The manga is very refreshing but it also has some series moments (so far). I promise you'll enjoy this manga its extremely cute. If you liked Momoko Sensei's other work then you'll enjoy this one.
