Yall i think the second story was about a group of orphans living in an orphanage but the person whose in charge sleeps with the kids and the eldest one (kazu) decided to sacrifice his body for the safety of the other children, but while being in there he falls in love with one of the kids there (hiro) . And you know how when you become an adult you have( or you can) leave the orphanage. The story is told from the perspective of the other kid who fell in love with the eldest (hiro). And when its time for the eldest to leave he asked the eldest to sleep with him one last time as a memory and that in return he will make sure to do his part and protect the other kids by offering his body to the one whose in charge ( the same thing the eldest did). And before the eldest leaves, he was keeping a diary, he gave the diary to the other kid( hiro) which had his true feelings in them. That said that he feels the same way as him.
