hi im looking for this manga

im kinda vague about it

genre josei, oneshot

a popular college girl who lives alone
one night she surprised by a cockroach 😭
then she quickly went outside and met an ojisan who just got home. she asked him for help to eliminate the pest. that night she stayed in the ojisan next door because she’s too afraid to sleep at her own place. long story short later they had relationships

pls letme know if you know heheh thx 🙏🙏

Does this "ojisan" actually look his age in the art or is this more of a general age gap story?
