>Could you elaborate on that?

If the active person in the message was Kasuga, then wouldn't the message be sent to 春日?
Are they talking to 春日 on an instant messaging app (which looks like LINE to me)?
Also, I've never heard 春日 hates big chests that much and I tried googling it but I couldn't find any clues at all.

The above is what makes me confused.

By the way, this is my personal opinion, but 髪の毛を生やす sounds like you grow your hair from a state of having no hair on the head.
Is 髪の毛を伸ばす not a more natural and better way of expressing you grow your hair longer?
