They literally drew a star on the horse's head... Facepalm moment (⊙…⊙ )

Yes, however, I'm extremely pleased to see the horse actually looks like a horse instead of a horse-like creature with elongated hippo legs.

Haha, very true!

My grandmother once had taken care of a horse who has the exact same mark like at the manga

You'd be surprised on how common these marks are on their forehead and stomach owo
