Like Attracts Love (KIDA Bisco)

Kuramochi Yuu is a salaryman whose number of years without a lover equals to the number of years he's been living.

On his way back from work on his 30th birthday, he decided to stop by the small restaurant he usually frequents to drink his problems away. While there, he was given a hard time by Kajii Rintarou, a bright and outgoing young man.

Yuu thought that Rintarou was someone who lived in a totally different world from him but they surprisingly hit it off once they started talking about their shared hobby.

But when he woke up the next morning, he found Rintarou sleeping in bed next to him!?
