Summary
You first see it when you’re half-distracted, slamming numbing palms into walls to see just one more secret, one more passage. You open the first door you see and it’s there, greyed out and hollow, not so much standing as just existing in the center of the room. Its face looks cracked, forever stuck in unmoving pieces, a stillness so unnatural that it sends a bolt of fear through your chest. You freeze. It doesn’t react.

Summary
Soulmates, oh sweet soulmates! Each and every person hopes to find the person destined for them.
Or at least, that's what they used to do, now that humanity has lost its magic after the war (War? What war?) soulmates have only become a cute fairy tale or an expression of love for the wrong person. And how can you blame them, if you've spent your whole life without knowing about the existence of such a thing, you can't expect everyone to give the deserved value to a word like 'Soulmates'.
But hey, what was that noise?!
It seems like an entire civilization of monsters has come out of the mountain! (And for some reason, it seems that somehow there are similar copies of each monster?!) What a scandal! The world is in panic, there are humans against it, there are humans in favor... While you feel something inside your ribcage pounding hard, trying to escape towards the mountain... In my opinion, maybe you want to see a Doctor.

Summary
When you decided to stay in Ebbot City, you didn’t expect your life to intertwine with monsters—let alone fall in love with them. What began as simple friendship soon unfolds into something far deeper, as familiar faces begin arriving from unfamiliar worlds.
In a home filled with secrets, laughter, and quiet heartache, you’re drawn into a web of connection that transcends timelines. But love is never simple, and in a multiverse of infinite versions, learning who to trust—and how to hold it all together—might be your greatest challenge yet.
Because sometimes, the most powerful thing you can offer… is your heart.
