The author hinted at it yes, WHEN THEYRE OLDER. Because I follow the author on twitter thats how I know. This is just a story about a ten year old developing his first crush. Some people are taking it too far yes, but people are weird all over the world. People getting angry at the author for content that isn't even in this manga.
Girl your replies are not helping your case "your all clearly waiting for it to turn sexual" lol what. You cant blanket blame thousands of people, your also not the hero for thinking that it turning sexual would be bad. If you read a majority of the comments you would understand that we would like sexual content after a time skip when they are of age or not at all.
this will develop into sum sexual i just BET it will, people defending this so bad like
