kyo liked rintarou since kindergarten, showed in koishite daddy. but rintarou likes his dad's lover since young. when he finally gave up on him, kyo confessed but rintarou dont seem to like him that way. until kyo decided to study overseas with an ulterior motive; to let him think of him a lot when he suddenly disappeared, because they were always together. rintarou then came to realise his feelings for kyo.
Love Kids!!
