It seems Lychee has a lot on her mind... she doesnt take time for herself or to express her emotions, and as a result has frequent mental breakdowns.

Kaliko being the gentle caring INFJ type that he is, his autism causes him to take things literally, the term "lending an ear" went straight to his CPU and as a result thinks that you litterally have to give the recipient your own physical ear... Not quite Kaliko, not quite.... still... im sure Lychee is more than appreciative of his attentive company.
