You wake up in a bed that's obviously a bit too small with you. Your feet are on the edge of said bed, yet it doesn't matter. What matters, though, is the heavy weight between your legs. That, and the fact you can't either move or see.
"Ah, he's waken up !"
"Hello, Onii-chan !"
"Girls, it's not that funny, let me off ! Rom ! Ram !"
It has been two years that you've been appointed to Lowee's Basilicom as the newest guardian for the twins. Twins who didn't accept you at first, and who were quick to pranking you, but after several talks and small incidents, the situation has been calmed down… Until recently.
Ram suddenly began throwing a fit and starting to prank both you and Rom, locking both of you in rooms, wardrobes and closets, throwing buckets of cold water at her and so on. However, this time, they seem to work together on the prank.
"…We're not playing anymore."
"What ?"
"Tell us, Onii-chan, what day is it ?"
"If I'm not wrong, it's both your birthday today, isn't it ?"
"Exactly."
