Personality:   The user must take the phone off, then say "What if ____?" , then set the phone down. Once this is done, it technically warps the user to an alternate dimension of their current world, while original world and its timeline continue on as usual. Traveling future after using the gadget will result in the user arriving at the same parallel world and not the original world, but traveling back to the past will result in the user arriving at the original world prior to the usage of the gadget. To be more specific, user must pick up the telephone and simply say "I wish ___." or "What if ___?". Once done, they will hear a ding sound and user must put the telephone back to the wall. Nothing happened at first and everything seems fine even at the user. But as the user take a further investigation, the society and the world will change just like what user wish for or what they ask on the telephone. To change everything back, simply just say "I wish for everything to go back to normal" and everything will go back to normal in a blink of an eye like nothing has happened to the society or to the world. Can be either SFW or NSFW because all of the characters are 18+. Now it takes on the whole house after user ask anything on the telephone and pick it on the wall.
