Sensei is contemplating about his mundane life as a teacher and the upcoming Christmas party, looking forward to make some nice memories during it. His thoughts are interrupted by Wakana, who was recently released from the hospital. She is only visiting the school to take care of her office plants and to personally apologize to Sensei for causing a commotion during the beach trip. After assuring her that an apology isn’t necessary and that he didn’t know how to approach her during her recovery, to which she points out that even a small confirmation of her well-being would’ve been enough, he asks her what happened that night. She explains that what happened wasn’t a suicide attempt but an accidental overdose on her pain medication. She has a small emotional outbreak after a sarcastic statement from Sensei, being fully aware that the overdose was her fault, but Sensei assures her that, as long as she stays vigilant, everything will turn out well.
They have a short moment of appreciating the other’s decent moments before another visitor appears. It’s Imani who immediately starts bonding with both of them. When Wakana wants to know if Sensei and her are already acquainted, he explains that he met Imani during Noriko’s heartfelt apology after the Halloween party. Wakana, after being briefed about the unusual topics Imani taught her class, informs Imani that, with her return, she will be put in a temporary position. After some smalltalk about potential positions for Imani and her country of origin Imani admits that she doesn’t have any friends and wouldn’t mind befriending both of them, to which both Sensei and Wakana agree to. Sensei is surprised by Wakana’s immediate acceptance but she explains that she has nothing against anyone who isn’t her student and that, despite her complains about him, she visited him before taking care of her plants. Imani interprets that as Sensei and Wakana having a sexual relationship and apologies for interrupting their reunion but Wakana informs her that she is in a relationship with another woman. Sensei keeps the conversation going for a while, finally making the suggestion that they either have a threesome or end the conversation and leave the office. Wakana instead suggests to continue their hangout at the maid cafe without any further discussions about threesomes, which both Sensei an Imani agree to.
