Please Take Care of the Baby!

It’s obviously wiggling on my bed… “Baby?”
Elena Velotte, an ordinary academy student, tried to rest well for a long time after the final exam, but a strange baby appears in her room.
Elena, who suddenly raised a child with Felix, a childhood friend and one of the best geniuses at the academy.
“Oh, Boo, Boo!”
But the kid is so cute! Besides, Felix, who she thought was only rough, also showed a soft side to the child…
“Okay? Oh, hey, hey. You can’t touch it.”
But the surprise didn’t end there.
“Stay by my side…”
Felix, whom she thought only as a friend for a long time, started to get weird?
