Honestly to start off an extremely insane title card not to mention how it all falls together. You wouldn't expect a anime with such a surprising title to be so psychological when it's based around comedy, slight fan service and past whatnot but this particular anime is just way more deep then I thought it would be.
Give or take I assumed it was going to be like the usual "Oh, we have to act like siblings now so theres gonna be a lot of awkward moments, tension etc" from the first couple episodes it's pretty light hearted with how they both go about it even with their past being so present. If you ever don't have anything to watch give it a shot cause it isn't anywhere near bad it is just a shock when you look at it.
