It is implied that an adult male teacher has been developing an interest in one of the male students he is teaching. He begins to sensually caress his face and tries to kiss him, until one of his classmates intervenes (21:40-23:20). Although the boy does not seem irritated. There are instances where the protagonist kisses the love interest at a time when the interest is clearly hesitant/unwilling to accept his advances. At times the protagonist also oversteps the love interest's boundaries and behaves in a fashion which might be perceived as sexually intimidating and aggressive. A teacher tries to kiss one of the students but it is broken up by another student walking in and stopping the teacher. Another scene later on features the same teacher talking explicitly about sex with one of these two students yet again. These students are maybe 17-18,. The rest of the manga also features heavy topics about student/teacher relationships.
