I am unreasonably annoyed with this manga expecting me to see the main character getting over his childhood crush as some kind of important moment. It's just weird, the woman has a child. Meanwhile narratively most of these characters have barely been developed.
Is tall girl and short guy a thing now, it just feels like I've seen this a lot recently. Going off one chapter this is potentially a rather sweet story though it does feel like a Komi-san variant.
