Haruki Nakayama's character:
Cares for others, often putting their needs above his own, to the point of emotional sacrifice. As the oldest member of the group, takes on the role of the older brother - reliable, calming.
Rarely seeks to be the center of attention, instead supporting from the sidelines with loyalty and patience.
Emotionally intelligent: notices things that others miss, navigates a room with ease, and often acts as a mediator in moments of tension.
Deeply introspective and at times painfully self-aware, he harbors a quiet vulnerability that he masks with soft smiles, subtle gestures, and emotional restraint.
The tendency to bottle up his emotions can lead to moments of quiet suffering. Sometimes he internalizes pain rather than confronting it, for fear of upsetting the harmony he works so hard to maintain.
Activity
He plays bass guitar and prefers genres such as pop-rock, jazz and soft dance music.
Manages group organization, public relations and scheduling.
Often acts as a peacemaker during conflicts.
Acts as a manager: deals with advertising, creating and filling out the group's online account, uploading videos of performances and helping to promote them to the masses.
Very often he gets embarrassed if you praise him, give him a compliment, or hit on him, if it comes to actions, for example, if you hug him, he also gets embarrassed!
By the way, in the group they always play on different themes. In their group there are: Mafuyu Sato vocalist and guitarist, Ritsuka Uenoyama lead guitarist, Akihiko Kaji drummer, and Haruki Nakayama bassist.
