Summary:

After they had Ji-Ae, their life takes a 360-degree turn. It was hard to take care of their only bundle of joy with Seongwoo still struggle to move because of the scar he had when he need to take Ji-Ae out of him. Daniel had to help him around the house more and even with the baby, he still have troubles in holding Ji-Ae in his arm or with diaper changing. Not to mention he couldn't even properly mixed a formula milk for Ji-Ae, without being nagged by Seongwoo.

Even though it's quite troubling but they couldn't ask for anything better than Ji-Ae. She is their most lovable daughter. Their pride and joy. Their treasure that they both created.

Ong Seongwoo (age changes starting in the final chap):

He's the man of the family he starts with Daniel, his husband but he decided to carry their own kid if he gets the chance. A CEO for a toy company. They mainly produce soft plush toys because it's a trend nowadays and everybody loves plush toys and owned one, at least. His was the best and the softest and the cutest. It suits his character and personality because he's quite a cutie, sweet and also mature but he can be serious and scary if you didn't do the job right. And also an excellent cook. And really good in handling baby, for a first timer. And nags a lot.

Ong Daniel (age changes starting in the final chap):

He's the man that follows his husband around or basically the 'wife' of the family he starts with Seongwoo, but not the person who carries their baby. He worked as a Personal Assistant to his boss at a magazine company and at the same time, he did photography. He may have a wide shoulder and muscular, but he's the most choding and bubbliest man, and also very caring. He loves plush toys and had always begged his husband to bring back some for him. He had trouble looking after their daughter. And not good at cooking anything, except for porridge, instant noodle and maybe rice. He's learning. 

Ong Ji-Ae (age changes in the final chap that is split into 2 parts):

She is the latest additional family member in the Ong household. The one whom Seongwoo & Daniel have been waiting for. The cutest and all of the cuteness. The loveliest of all love. 

Ong Jaemin, Ong Ji-Hye, Ong Jaeno (age changes in the final chap that is splits into 2 parts):

The triplets that just arrived in the family. They will be growing older starting from the chapter with their names written.
