Yui playfully blows fog on the walk back from a public bathhouse.
One Room is the anime short this season offering "the girlfriend experience" with three different girls. First up is Yui, who needs a little math tutoring from her hot ikkemen neighbor. That's supposed to be you, stud.
How convenient that construction shuts off the water so you and your cute neighbor have to go to a public bathhouse.
Convenient... for this show.
