Synopsis: Isso Koe ga Nakattara

Ruri Rokuse faces a challenge when dealing with strangers due to his stuttering, but he finds solace in his part-time job as a janitor where communication is minimal. Tooru Takashina, an office worker in his building, is someone he looks up to because of his ability to speak fluently in public. Ruri admires Tooru's poise but believes he can never possess such charisma. When Ruri finds Tooru's lost flash drive at work, he musters the courage to approach him despite his speech impediment. Although he quickly runs off after speaking, Tooru doesn't seem to mind and expresses his gratitude for returning the item. The two cross paths again, and with mutual support, will they be able to overcome their barriers and communicate effectively?
