Hehe that was so cute. I really like the mangaka's artwork, especially her style of drawing chibis, they're so funny and adorable~
There isn't much of a story here, rather just a short cut of life for these two. I'd say this is a decent doujinshi, and though I'm not always familiar with the concept of Haru being the seme, I gotta say the author did a good job of surprising me with how natural it fees.
