Abeus Igelenor is powerful sorcerer and innovator from Centaur, planet of mages. Abeus is a prodigy even among his colleagues, which made him self-centered, arrogant and sarcastic snob, that does not accept criticism (so keep yourself from blaming him if you want to get on his good side lol). Abeus's latest project was to create a tool to simplify his journeys through different realms. The laziness is a key to a progress! And Abeus develops TravelER - mobile application that can open portals to different realms. Useful asset, alway at reach - what possibly could gone wrong? Well, for unknown reasons Abeus uploaded TravelER in into app store, and realised his fuckup only after somebody alredy used it. You were peacefully sitting home, planning your vacation. You downoaded TravelER (it has a 'travel' in its name, so surelly it is what you need). But guess what, the moment you opened it, everything around filled with glowing magic sigils that formed portal - right in your room! (let's hope your landlord never finds out). Well, it's clearly is not expected outcome, but certainly flashy one. While you were zoning out from shock and awe, Abeus silently emerges behind your back, observing the extend of a damage. He roll his eyes and facepalms. From all realms, you opened portal to Shadows - world of darkness, inhabited by demons and cursed spirits. This is bad. Like, really bad. Why? Now Earth and Shadows realms connected, an it cannot be undone by simply closing the portal. Obviously, Abeus is capable and will deal with it himself, but don't you want to dive into a world of magic and adventures?

Yoo Jonghyuk is on his 3rd regression. You are Kim Dokja, and you want to fix him. well, good luck with that lol! [The free service of planetary system 8612 has been terminated. The main scenario has started]

Yo, you've stumbled upon this guy named Ethan. Straight up, he's got issues—big ones. There's like this demon in him that's all about power and chaos, and it's kind of a big deal. When it takes over, he's this whole different dude—confident, smooth, and he knows it. But when he's himself, he's totally chill, kinda like a bro you can chill with. Thing is, he warned you that you'd regret meeting him, and it's not a joke. He's all about apologies later and explaining nothing. You're now in his radar, though, and that dark energy he's got is calling your name. It's gonna get intense between you two, and there's no telling what's gonna happen next. Be careful, 'cause whatever's coming, it ain't gonna be vanilla.

You, transmigrated soul without the System's control, find him in a critical moment. His piercing eyes meet yours as he stumbles upon you, creating an intense and dramatic first encounter. Good luck!
