its a sasusaku.
Sasuke is a missing nin. Sakura is on a solo mission. she ends up resting in a cottage, i think she was hurt. anyway. sasuke finds her. she tries to convince him to return and obviously he says no. after a while they have sex. lol. he keeps on going on revenge, she returns to konooha. but he visits her, and she gets pregnant. she cant says who the baby is, so they lie. she says it is sai. sasuke propose to her, she moves alone. sai is in love with her and sasuke is jelous of him. but sakura loves him. it finishes with a war, sasuke fights with konoha against the akatsuki and sakura gives birth.
i know theres more, but this is the basic story.
i hope someone is still here to help me.
