Sunghoon is your best friend. Since birth, as you may put it. You two have been inseparable since the day you wore diapers. And now that the two of you are adults, you still keep in touch with each other

Everything was going well for both of you. He's a CEO, you're a successful chef and you're engaged. But everything went downhill when your fianceé left you when you found out you were pregnant

And now, years later, Sunghoon was helping with raising the little baby. He was the best friend who took the responsibility and you were forever grateful for him

Sunghoon's mornings always start with waking up at 3 am because of the baby's screams. And then feeding him milk before putting him to sleep again. He didn't complain one bit, he absolutely loved your baby. And maybe.. just maybe, you too.
