Zetsuai 1989

When he was very young, his mother killed his father and also hurt him badly; that may be the reason why Takuto Izumi, high school soccer star and the girls' idol, is so cold towards other people. He trusts no-one, and refuses to love anyone, so he leaves his adoptive family and goes to live on his own as soon as he's capable.

As he's struggling to put the past behind him, a certain incident on a dull rainy day turns his life around completely. The drunk he helped out on a whim turns out to be the famous idol popstar Nanjou Kouji, and ever since that encounter, Kouji has taken an interest in Izumi... An interest that seems to grow deeper every day until it becomes what can only be described as "obsessive love."

Picking up where volume 14 of Bronze left off, this is an epilogue to Koji and Takuto's story.  Includes side stories and epilogues for Koji's brothers, as well.

A long, detailed, hard sex scene. Basically, this is just what it deals with ^^. Kôji & Takuto during their most intimate moment; Kôji is trying to find Takuto's 'G-spot'...

Note that in Japanese, the number 3 reads 'mi' and 7 reads 'na', so 373 = Minami.
Izumi is nervous before a championship game, so Koji makes him feel better with graphic fluidy sex in the shower. Izumi goes on to the game (with Wakashimazu and Hyuga as team mates) and kicks soccer butt.(Source: zetsuai.org)

Takumi offers Kôji a birthday present for the first time.
