A Good Day To Be A Dog is based off the webtoon of the same name. Covering the events of the original webtoon, you play as Hana Han, a teacher at Garam High School who has a terrible secret. If she kisses someone, she'll turn into a dog every subsequent night until she kisses them again in that form! Struggling to find out the events of what happened that drunken night, she has to figure out which of the three men she kissed. Will she ever get rid of this horrid curse?
