Tengo is the seme of the decade. He was always so polite he loved and waited for Yoshioka to be conmfortable. He never pressured him, and was always so respectful about Yoshioka's feelings.
I'm sooo happy they could move on together and be the absolutely fantastic couple they are. Also, the couple when Tengo became professor was cuteee.
