Do you want to know something you don’t know?

The protagonist’s grandfather, who ran a model kit shop, falls ill, prompting him to take over the business. One day, Risa, a regular customer and model kit enthusiast with an impressive figure, offers to work part-time at the shop. Thanks to Risa’s strict but reliable support, the shop successfully reopens. One day, the protagonist discovers a special solvent created by his grandfather. While chatting after work, Risa casually starts changing her clothes in front of him. Shocked, the protagonist accidentally spills the solvent on her. As he nervously apologizes, Risa’s demeanor changes dramatically, becoming seductive. With her body burning with desire, she approaches him and, with her ample chest exposed, whispers, “Please… could you satisfy me?” And so begins an unexpected scene of passion!

The tsundere and voluptuous employee, Risa, has the day off, leaving the shop completely empty. Feeling bored, I decide to pass the time by watching videos of a popular, busty streamer, Misaki Tsukishima. As I get lost in memories of the passionate encounter I had with Risa a few days ago… Misaki suddenly appears in the shop in person! Although she notices I was watching her videos, Misaki remains friendly and, with a suggestive attitude, starts teaching me some tips about model kits. However, as we chat, I accidentally inhale the scent of that mysterious solvent. Before I know it, my desire completely overtakes me, and I pounce on Misaki… sparking yet another unexpected and fiery situation!
