Im starting to see Sachi is more mature than Erika which verifies Hotel King Dads claim of Sachi preserving everything if she and Nagi marries.

My theory is that Erika keeps living in an illusion of being a kid with an "imaginary" older brother since she was raised alone in actual reality. Since Erika has not developed mentally, Sachi surpasses Erika in the older sister aspect. THE IRONY.

Just a theory ,but could Erika be suffering from an illusionary mental illness illusion of having an older brother and Nagi's dad already knows this thats why he offered Nagi the other alternative to continue the bloodline through his younger non blood related sister of marriage?

They key to this will be that recent Beach House, height wall carving and that suspicious game saved, is my assumption.

So Erika may not have all that screws in place and for Nagi's own safety, his dad hinted it might be safer for him to marry his younger non blood related sister.....

If thats the case, then did Erika see ghosts?

Nagi's decision and marriage to:

1. Erika

2.Sachi

3. Hiro (allegedly)

4. Ai

Who does nagi stay with and marry?

Does anyone know the sountrack of episode 2 from A couple of cuckoos? I really like some of the music on there.

I need to know something. Is there any arc in this manga?

Another romance comdey to enjoy and fight over which girl is better. May the best girl win.
