Was I the only one that noticed how tastuyuki also featured in the authors other manga "minori no te" where minori sensei massaged him.
And Tatsuyuki says Minori's name several times, thinks about him, imagines he sees him, tells Nozomi about him, Nozomi offers to be Minori's surrogate. All kind of give it away.
If only it wasn't shounen ai ┗( T﹏T )┛
