Hirotaka Wakamatsu (若松 博隆 Wakamatsu Hirotaka) is one of the heroes of the series. He is in class 1-D, and is one of Nozaki's friends from their basketball team in middle school. He joins Nozaki's staff initially to do erasing,but later on to do tone work. He claims that the only person he cannot stand is Yuzuki Seo, which is somewhat ironic due to the fact he is a fan of the Choir Club's Lorelei, who is actually Seo herself. Strangely, though he has chronic insomnia, he falls asleep within a few seconds when listening to her calming songs.
Wakamatsu is a tall high school student with short messy plum purple hair and blue eyes. When participating in club activities, he wears a blue and yellow basketball uniform. When outside club activities, he wears his school uniform, a white blouse with the top button undone with a loose green tie and green cardigan alongside a pair of navy dress pants with a brown belt and brown shoes.
Wakamatsu is easygoing, but he can be naive and has a tendency to take things at face value. For example, in an attempt to stand up to Seo, he consults Nozaki and his collection of shoujo manga on how to do so. This leads to him sending Seo a love letter, rather than a letter of challenge. He also compares her to his "Goddess," the Lorelei of the Glee Club (who is Seo herself), in order to try to put her down.
He's very sensitive and gets emotionally hurt very easily. When things don't work out for him, he never seems to understand why or what went wrong.
His combination of sensitivity, energy and naivety can make him do extreme or unexpected things. His friends do not trust him with a knife because they are scared he might kill someone.
Yuzuki is the only person that Wakamatsu claims he cannot stand due to the fact that she terrorizes the male basketball team, which had caused Wakamatsu to develop insomnia. Ironically, despite being the cause of his stress, she is also the cure, as just by listening to her singing for a few seconds he can go to sleep. Because of this, he claims that Lorelei is his "Goddess".
Wakamatsu also claims that Seo often buys souvenirs and gifts for him, as well as asks him to hang out with her (to catch a movie, etc.), despite his claims that Seo mistreats him and is a bad person. Although Seo is the main source of his mental stress, he apparently does not, in fact, hate Seo, and would feel uncomfortable whenever he hears that Seo hung out with other boys.
Nozaki was the captain of the basketball team of his middle school, and they have known each other ever since in middle school. Wakamatsu looks up to Nozaki as his senior in both school and in basketball, and often tries to get Nozaki to play basketball again. Due to this, he often gives in and offers help to Nozaki, leading to Wakamatsu becoming Nozaki's screen tone assistant. Nozaki is very determined in hiding Lorelei's true identity from him.
Hori and Wakamatsu met each other as Nozaki's assistants when he texted them on a sick day. They also work together sometimes since they work on the manga late, Hori because of his club and Wakamatsu for his insomnia.
Wakamatsu first thought that Kashima was Yuzuki's boyfirend, after going swimsuit shopping with the girls and being told the truth of her gender by Nozaki, he is embarrassed. In an attempt to boost his metal fortitude, he goes to the drama club for tips but things don't go well. Because of these circumstances, Kashima believes that Wakamatsu is an idiot.
Both are aware of the other being an assistant. He shows immense support for Sakura and Nozaki upon hearing about her crush, prioritizing it over his own love life. Sakura acts kindly towards Wakamatsu as a senpai and considers him and Yuzuki to be very close.
Wakamatsu looks up to Mikoshibal and thinks he is a "very cool" senpai. They later find out the other is an assistant and Mikoshiba becomes more open and trusting with him.
Wakamatsu and Mayu meet once at Nozaki's Apartment. They bond because they are both athletes dedicated to their sport, and Mayu attends the same Middle School that Umetarou and Wakamatsu did. He believes that Mayu is the owner of Mikoshiba's collection in the apartment.
