Pairing: Makoto x Haruka

From Always Here Scanlations:

V1: Haru finds that watching his best friend almost drowning can change a lot of things about their relationship quite fast. On the surface it seems as if this is the catalyst for Makoto's sudden confession, but like the water Haru loves, it seems a lot is going on beneath the surface of Makoto's calm exterior.

V2: Makoto and Haru's relationship is growing, bit by bit. After a misunderstanding on Makoto's part, Haru assures him their feelings are mutual. Coach Sasabe manages to stumble in and ruin a sweet moment, however, he brings up some good advice that Haru takes to heart! Makoto and Haru feel ready to express their love in a more intimate manner, but first Makoto has to survive the trip to the pharmacy!

V2.5: After their first night together, Makoto and Haru engage in a bit of pillow talk. Haru soothes Makoto's worries, and Makoto just wants to take care of his lover. This is...definitely okay with Haru.
