Nariyuki Yuiga

She has significant conflicts with him regarding his tutorship, in the beginning, disagreeing with his methods and attempts to encourage preference over talent.

She is very open towards him as he knows much about her embarrassing side that she hides from everyone else. He often visits her apartment, sometimes of his own accord, sometimes when she invites him because of her 'troubles'.

She cares very much about him as a teacher and often helps him with his studies or treats him with food due to him helping her out on resolving the 'blunders'. Its often hinted that she is developing feelings for him with every 'blunder' though she puts up a front when facing him. She scolds Miharu when she talks bad about Nariyuki. She even confronts the headmaster upon knowing that they have accepted withdrawing his VIP recommendation application.

Throughout the series, there have been many occasions of physical contact between the two which resulted in Nariyuki becoming somewhat conscious of the beautiful, charming adult sensei. He often encourages her in many instances and tries to make her happy.

She has some breakthroughs in the relationship in recent chapters, she finds that Nariyuki's teaching methods are similar to his late father. She recalled her memories on her school life, influenced by Nariyuki's Dad on the decision of studying education. She later agrees with Nariyuki to attain education.

As of Question 133, their relationship has deepened to the point where Nariyuki felt as if he was talking to the high-school version of Mafuyu when he mentions he likes midwinter (Mafuyu roughly means midwinter) and she asks which midwinter, pointing at her name. It is heavily hinted that at this point she has developed some sort of interest into Nariyuki.

Asumi Kominami

She met Asumi in High Stage where Nariyuki was studying during a summer course.

During her time as Asumi's teacher, she disapproved of Asumi trying to get into medical school, as Asumi failed in admission tests and had poor science results.
