Koishi Komeiji's Heart-Pounding Service Disc (Bonus Track!!)

This story takes place between Track 1 and Track 2 of the main story. It's listed as a bonus, but without it, things jump abruptly from a waking-up scene straight to a bath scene, so it might be better to buy this one too if you can. It costs a bit extra, but there are plenty of sweet scenes like making miso soup together with Koishi and feeding each other rice, so before I knew it I'd listened to it dozens of times. She doesn't seem to understand what "service" really means, and just keeps endlessly being clingy and sweet, which is genuinely adorable. Like a puppy.

On top of being healing, it really gets your imagination going. You just end up squirming, unable to stand it! I'd already bought the CD, but since this was a limited release, I made sure to properly purchase and listen to this one as well. Listening to them together, the sweet fantasies with Koishi just keep overflowing and won't stop.

This is probably the story that takes place between Track 1 and Track 2 of the main story. Koishi happily feeds you food. When it was your turn to feed her instead, she seemed really delighted, which felt very true to Koishi's character. She also brags about her sister here and there throughout, which was really heartwarming to listen to. It's a bit pricey, but if you liked the main story, I recommend listening to this alongside it.
