Title: Makes hair grow

Wall Iris: Since I already bought some cake, let's take a break!
Japanese Felwort: I made some tea~
Wall Iris: Thank you very mu... BITTER...!?
Wall Iris: How did you make this tea so bitter...!?
Japanese Felwort: ...Ah, all the tea I make somehow ends up really bitter like that. All that bitterness made me grow extra hair. ...is something that people say. <Fufu>
Japanese Felwort: Then again I think it wakes you up nicely and makes for a great refresh.
Wall Iris: I think saying it makes your hair grow is really going too far... but you're right in saying it makes you feel refreshed! <hair sprouted>
Japanese Felwort: I'm glad to hear that ♪
