This is so cute it's making me stupid. I love how the translator captured all the kiddie speak so well and the art is just boss. Love love fluffy love this.
I don't even know if I should tag this as a Shounen Ai because it was more of a beautiful friendship told through snapshots from babies to teenagers and there was no actual BL dialogue or angst in it. The mangaka did somehow capture a deeper connection than just friendship so I'm hoping he/she continues with this storyline and develops these characters further.
