it's kinda meh, I mean I've read quite a few of yaoi where their childhood friends but their different in the future, well the Seme is different. The school though it really cute. Honestly I'd prefer to see the two kids later on too grow up and see their relationship.
Natsumichi Drive
This was super cute and ofcause sex spa scene ;) almost can’t have a yaoi without one heh xP The side story was also very cute and I feel it could have been more in depth.... actually both stories could be. It's a little intense and get the job done.
