Why is Usagi jealous of Chibi-Usa?
Jealousy is very natural for everyone. Usagi isn’t jealous of Chibi-Usa because she thinks Chibi-Usa will steal Mamoru away from her but she is mostly jealous because Chibi-Usa does take away some of the time that Usagi and Mamoru spend together. Also, Usagi sometimes feels that Mamoru cares more about Chibi-Usa than her. However, Usagi really knows that this isn’t true. Chibi-Usa is her and Mamoru’s daughter and they both love her dearly. She also knows that Chibi-Usa’s “crush” on Mamoru is really Chibi-Usa’s way to deal with missing her real father, King Endymion.
