Heartwarming / ATTACK on MIKA

• Makoto lost his mother a week before the parents observation day. His aunt disguised herself as his mother and attended the event so he won't feel sad on the day. Years later, Makoto found out about it and thanked his aunt.
• Aira's close relationship with her fiancé Taizo's mother, Keiko. Aira lost her mother when she was young, and recently lost her father as well, and Aira and Keiko treat each other as actual mother and daughter. When Aira discovers Taizo has been cheating on her, Keiko is fully on Aira's side, fully supportive of Aira breaking things off with her son, and the two are still as close as a real mother and daughter afterward. To add even more heartwarming, Konomi, the mistress Taizo was cheating on Aira with, was completely unaware about Aira, and afterward, Konomi became good friends with Aira and Keiko as well.
