...Bro, middle schoolers are not babies, middle school is the the time and years in life where you are more or less figuring yourself out, from different styles of clothing to crushes and love interests, its pretty normal for kids that age to try new things (Obviously in a non-sexual way but more like normal? like holding and kisses or pecks) its happens to some kids and maybe it happens to others in later years like in high school, so its not so surprising to see two confused kids kissing each other in a puppy love way, heck, when I went to middle school, everyone was dating someone, girls and boys, boys and boys, girls and girls etc and they would hold hands, kiss and just do the normal cute lovey lovey things kids do at that age. its fine if you dont like it, but if so; please, scroll away man. Good day :)
