Story of My Rival, Her Sister:

After meeting the love of your life, you finally feel like everything is falling into place.

You have a relationship you care about, a career you’re trying to build, and a stable routine that makes life feel almost perfect.

But things don’t stay simple for long.

Your girlfriend’s sister ends up moving in with you, turning what should have been a comfortable new chapter of your life into something much more complicated.

Living under the same roof changes the dynamic between everyone. Small misunderstandings become awkward situations, boundaries become harder to maintain, and one embarrassing mistake is enough to turn an ordinary day into a completely different kind of problem.

From there, the story begins to unfold through the relationships between the characters, their personalities, their choices, and the situations they find themselves in.

And sometimes, the person who causes you the most trouble is the person you least expected.

Player Comments of My Rival, Her Sister:

The fade to black multiple times for the bathroom scene is very jarring and imo, unnecessary. Not sure why it happens like 4 times in a row. Also, could you clarify what's up with the female protagonist tag? Also, are any/all sexual situations optional/avoidable?Too little to tell right now, need to see more. But honestly, it was a decent intro to get me intrigued, assuming clarification comes on tags, number of LIs, kinks, harem/not, etc.

Best of luck, whatever the answers are, and I'll keep an eye on things here. The premise seems interesting and the girls look cute, and as long as the no NTR things and eventual harem is accurate it seems like a game I'd really enjoy. But I never play games until a few release in at least for lots of reasons. Anyway, good luck.

I see you say Bruna's actions will be mainly directed towards MC, which is fine, but can we push it towards some lesbianism like with sister, maybe? Or nothing at all, cause wouldn't mind having choices for girl fun with her or other girls.I also seen we can make her a bit domiant with us, that sounds hot, like she is in control with some light femdom could be option, like her setting pace and maybe some light other kinks could be hot.But another idea I had is, what if Bruna helps turns her sister into a kind of cuckquean that gets off on watching MC a bit. Obviously doesn't have to stay watching, she can join in sometimes, but becomes a turn on that her sister is with her man and watching, could be fun idea.
