The Anime Lad
High school student Ichika helps salaryman Ryo during a chance meeting at a station. He later proposes a kiss or a date as repayment. She tells him he is creepy. Ryo becomes more interested and begins expressing his feelings repeatedly. Ichika continues insulting him with a consistency that the situation has done ample work to earn.
Super Eyepatch Fox
Help an older stranger at a station. Meet him again and receive an unwanted romantic offer as thanks. Ichika rejects Ryo and calls his behavior creepy. He treats her response as further reason to pursue her. Their comedy rests on his relentless attention and her refusal to disguise how unwelcome she finds it.
Gigguku
Ichika performs one kind act and gets rewarded with relentless attention from an older man. She does not soften her reaction or pretend his confidence is charming. She calls Ryo creepy and keeps saying what the situation deserves. That blunt resistance gives every exchange its energy, even while the age difference remains impossible to ignore.
Father's Basement
An adult salaryman pursuing a high school student is the central problem, not a decorative complication. The premise at least lets Ichika name that discomfort directly. She rejects Ryo’s advances and refuses to supply the flattering response he expects. Whether that is enough depends on how much persistence the viewer can tolerate.
