Emotionally stunted boy X emotionless girl, the manga. That's right, the premise is supposed to be that Akanabe sensei is a girl who can't feel embarrassment, but the truth is she shows no emotions at all, not just embarrassment. Apparently the author cannot tell the difference between not feeling embarrassment and not having a single ounce of humanity. The female lead will say stuff like "I'm so over the moon, you made me so happy" with a perfect poker face. Last time I checked happiness isn't embarrassment, but even when happy she reacts like an android. The male lead is even worse, the spineless romcom MC whoseknees get weak because of hug. Constantly turning beet red in the most mundane situations as if he were a middle schooler who had his first erection last week, just absolutely lacking in manliness.

On the other hand the story isn't that bad, but just kinda boring, nothing much really happens. The wholesome vibe is enjoyable but it does nothing to elevate the romance. It's best enjoyed as a cute slice of life basically.

As a slice of life it's pretty good, as a romcom it's pretty bad.
