Hahaha, nice.
Well Satoshi and Mayaka are not commenting on her closeness to Hotarou, and poor him can't complain out loud (I love the little details like a sweatdrop or moving an inch away), so I'm looking forward to their blooming romance.
On another note, can someone tell me if the name "Eru" is popular? Doesn't sound too similar to "erotica"?
