How to Love a LoserDame Ningen no Itoshikata

Shinba has no talent, no job, no money...he's a complete loser. However, he has a girlfriend, Hizumi who is beautiful, smart, good at her work. He has no idea why she says she likes him. He's almost scared, but loves Hizumi so much...he asks Hizumi, "Why do you want to date with someone like me?" She answers..."You always oversleep, talk about some video games I don't even know about, sing lame songs no one knows at karaoke, gave me a toy ring as a gift. Your face is always gloomy as hell. But...looking at such face makes me happy, Shinba. I love you, ha ha." Is she telling the truth? Hizumi must have some kind of a secret, Shinba thinks. He wants to find out...but maybe he shouldn't.
