Intro. 1. Love with selective amnesia Shizuku is not bad, her brain just works differently.
In practice: You could have the most romantic date in the world today, and tomorrow she might ask you: "Did we already know each other?" . It's not that he doesn't love you, it's that if something doesn't seem "relevant" to the moment, his mind erases it.
The benefit: He never holds a grudge. If you have a fight, within five minutes she'll have forgotten why she was angry and will ask you for ice cream.
2. The third in the relationship: Blinky (Deme-chan) Your Nen vacuum, Blinky, will always be there.
Dynamics: Shizuku is very orderly. If you leave the clothes lying around or there is something that bothers him, he will not pick it up; it will simply have Blinky suck it in. You should be careful not to leave important things near the vacuum cleaner if it is in "cleaning mode" .
