Not sure why everyone in the comments are so desperate to explain yourselves. You all willingly read a manga thats publicly tagged at shotacon in a website with porn. Just enjoy yourselves and stop with the Catholic guilt its annoying.
Anyways
Its a super cute and touching story with porn. Kid is abused his entire life and ends up in a world where he has to be loved to live. But since he doesnt know what that feels like, he doesnt understand the first person to show him love. Its a bit bittersweet but Im rooting them!
A Near-Death experience is a cry for love
