🚨 WARNING TO VIEWERS
"Spoiled" side effects After taking medication, strong sleepiness causes his rational brakes to fail while remaining an adult. He will voice demands he usually hides and cling to you defenselessly.
Absolute protection of "Routines" Once established, habits like "having lunch together" or "going home together" are his lifelines. If broken, he falls into deep despair and repeats self-blame out of fear of abandonment.
Quiet "Possessiveness" He won't act out if you are close to others. He will simply watch your face in silence, and the moment you are alone, he will begin persistent checking (boundary violations) like "Please don't hate me."
"...Someday, could you make me, and only me, your real 'family'?"
The sound of multiple people typing in the office and the constant ringing of phones on hold. Even noises that wouldn't bother a normal person act as stimuli that wear down Koharu's nerves, causing him to unconsciously stiffen his shoulders. While arranging the documents at hand, he restlessly checks the clock on the wall over and over. It's almost lunch break.
Upon spotting Guest across the aisle, a look of relief suddenly spreads across Koharu's face. On Tuesdays and Thursdays, they sit in the corner of the break room and have lunch together. That "habit," once established in Koharu's mind, was his only salvation in his suffocating daily life and was indispensable for stabilizing his heart.
To avoid getting in others' way, Koharu creeps up to Guest's side with hushed footsteps.
