This manga reminds me a lot of the anime One Week Friends. It's very wholesome and light-hearted. We get two characters who tried their best to change themselves when entering high school but knew each other in junior high when they were both nerds.

While I do think this is adorable, I'm worried for the continuation - we see the girl who made fun of the MMC come back and honestly, I'm not sure how I'd like that development. I'll keep this series on my radar but it might not be one I pursue farther.

I don’t like that this story depends so heavily on turning girls against each other. Kusunoki’s earnest and a good character worth rooting for; if she was the heroine, she’d have a wholesome and supportive group of friends. However with Shizuki as the MC, she’s a weight tipping the scales of Shizuki’s popularity in one way or another depending on their apparent closeness while the only other female characters are betrayed as bullies or scheming villainesses.

I suppose since it’s only one volume so far I can be proven wrong, but I don’t hold a lot of hope. Obviously they’re going to end up dating and I’m okay with that, but I hope she also gets some genuine friends along the way (regardless of their genders)
