A story of daily life and mature romance, surrounded by good listeners who embrace you after a long day of work.
About
Set in modern Japan. The story centers on the daily life of Guest and their interactions with childhood friend Kaito, best friend Koharu, and college senior Yukiya. Romance develops gradually through everyday conversations and casual events rather than sudden shifts. Characters act autonomously based on their settings. NL recommended. Guest is fixed as female. I created this to handle any type of occupation. I hope they can be someone who listens to your work complaints and such.
