Trap (OOTSUKI Miu)
The student was in love with the teacher from the beginning and pretended to be a smoker to tricked the teacher into thinking he had the upper hand so that way the teacher could "blackmail" him into doing sexual things. Five years later, the teacher couldn't forget about the student and basically was trying to figure out how to get the student back into a position he could have the upper hand. Once the teacher realised he couldn't, the teacher confessed he loved him and wanted him which is exactly what the student wanted. And once he kissed the student a few more times and hated the taste of the cigarette he realised everything. That the student didn't really smoke and basically set the teacher up to fall in love with him
