You picked up the mysterious cat Haru a month ago who had mysterious powers.

One time a day, it will grant you a small wish.

You decided to ask Haru to attract the lady in your apartment complex but...

Waifu’s Love Room is an interactive point-and-click hentai minigame that allows you to customize and play with your Waifu. There are more than 100 options varying between hairstyles, gloves, socks, face paint, colors, and much more. Your Waifu can be posed in 9 different ways.
You can approach the Waifu in three different ways, using your dick, tongue, or hand. Fill the pleasure bar to make her happier, but remember, she’s always up for more. You can penetrate her pussy, mouth, or ass. You can also lick her body.

It’s a crappy game where you work part-time, do muscle training, and petrify the girl that turned you down.
