From Yaoi Is Life:

Takamine's parents failed in their business, and everything was lost in no time. He is then left to live in a shabby apartment with Shirahane, his caretaker since childhood. Why did he stay, when Takamine is no longer his master, why is Takamine getting erect, and why does Shirahane think it's splendid?

When it's love at first sight, your beloved sparkles right? Love makes everything sparkle...
