I think the ending was too rushed. A couple of chapters showing them bonding would've been nicer. Also, I don't like how conveniently gramma got killed off on the last chapter. Jaekyung being affectionate like that directly also seems a bit weird to me. Ik there will most likely be side stories but I wouldve personally preferred it if all the issues were solved in the main story.
