JUST ADD WATER Born with a congenital heart disease, and thus unable to join in activities that are too physical, Manga Club Captain Yoshimatsu Hotaka can only watch through the club room's window whenever the school swim team practices. Hotaka is enamored with swimming ace, Awaya Niki. But sickly, shy and extremely introverted, he feels all he can do is pine for her from afar. Seeing her as a sort of Goddess of Summer, he feels he isn't even worthy to share the same air with Niki, much less approach her. But when the gym teacher asks Hotaka to attend a special, after-school swim class to make up for not participating during regular classes-a supposed to be one-on-one student teacher session which the swim team unexpectedly crashes-it sets into motion events that may, quite surprisingly, result into Hotaka and Niki actually becoming friends.

SUMMER SUCKS! The rumors of Awaya Niki befriending Yoshimatsu Hotaka as a way to get closer to the class hunk, Soga Shunsuke, have reached Hotaka himself. A magical moment under the rain, however, reveals the truth. Everything soon takes a turn for the worse after a public confrontation between dear friends. Can't poor Hotaka ever get a break?

HOT AND COLD. SUN AND RAIN. Hotaka is at his wits’ end. Suddenly, improbably, he is befriended by Awaya Niki―the smoking queen of the swim team. But just as abruptly, she decides to drop out of his life without a warning. Though confounded and frustrated at first, Hotaka has resolved, by hook or by crook, to get an explanation on why Niki is avoiding him. But how is he to do that when she doesn’t answer his texts or his invitations to meet up and talk?

TO YOU, I GIVE ETERNITY A brainy manga club captain and a beautiful swim club’s ace seem like an improbable match. Yet despite their differences, Hotaka and Niki find that they have deep feelings for each other. Short after Niki’s confession, the two excitedly set their first date. They agree to go to a summer festival together. But shocking revelations about Niki’s true identity will drastically affect their relationship, in this heart-wrenching conclusion to the Evergreen series.
