Daisuke Niwa is an ordinary middle school student who has inherited an interesting family condition, where the sight of the girl he adores transforms him into a phantom thief.

    While he's away at work, mom Tomoko and her two beloved sons Hiroki and Yuri go about their everyday lives--going to school, making dinner, doing homework, etc. But now that Hiroki's in his first year of high school, his thoughts are turning ever so slightly to sex and romance...and his mom can't help but notice his slips of the tongue when he's talking about who he likes. Supportive Tomoko has an inkling Hiroki might be gay, but she's going to let him figure it out for himself. Unfortunately, Hiroki has little talent for keeping his "secret," so he might die of embarassment before all is said and done!
