I don't remember much from this manga. The main character gets confessed to by another boy, whom I think plays video games a lot? I remember the main character has friends with unique designs. They were nerdy and one had a afo-type hair style that reminded me of a skinny version of Tomohiro Nagatsuka from A Silent voice.(I think he had glasses too) I remember him going to the beach with the friends and eating watermelon.

And I'm not sure if this is in the same one, but I think the main character looks like another character in the confessers video game.

Sorry if it's very vague. I might even be getting the details wrong. My memory is crap, but I remember liking it and wanting to finish it, but forgot the name.
