Medium lived simple story of a younger guy who grew up with an older girl. They just visit each others places and interact normally unaware both of them are into each other? The chapters are super short so you could breeze through them without taking too long. There isnt really anything special here, both of the characters are about as normal as anyone else. Regular low key romance life between young people while time passes. It could be a bit simple for a theme of an MC with an older girl, so it's medium pace ending is just all right.
