   Summary

   Netaro had noticed the look on Nagi’s face whenever he pulled away from a kiss, the shine in his eyes whenever he leaned back again... it was only natural for Netaro to wonder what was the cause of Nagi’s excitement — he really wanted to see more of it.

   After thinking it through, he had come to a hypothesis, and was determined to put it to the test: could he be the direct cause of Nagi’s reactions?
