Synopsis

About Aharen-san is Indecipherable

Super quiet Aharen Reina isn’t great with personal space—she’s either inches from your face or too far to hear, leaving people totally baffled. But when Raido, the friendly guy seated next to her, helps retrieve a dropped eraser, Aharen suddenly wants to get closer to him. From that moment on, she’s constantly by his side. And surprisingly…he’s cool with it. This offbeat, sweet-natured rom-com proves that friendship—and maybe even something more—can bloom from the most awkward encounters.
