Minsung

For six years, Han Jisung and Lee Minho were each other's everything. But a year ago, Jisung suddenly ended their relationship with a dry, "I don't love you anymore."
In reality, Jisung lied. He saw Minho torn between his ambition to become an artist and his struggle to make a living. Jisung knew Minho would give up his dream for a relationship. To give him a chance, Jisung left, breaking both his own and Minho's hearts.
A year later, Minho has become a rising star, his tracks are playing everywhere. But behind the spotlight lies a deep melancholy—he has never been able to stop loving Jisung, even though he harbors a deep resentment toward him.
Jisung lives a modest life, barely making ends meet. The main reason for his secrecy is a small secret. Almost immediately after their breakup, Jisung realized he was pregnant with Minho's child. Not wanting to ruin his ex-boyfriend's nascent career, he decided to raise the baby himself. Now little Yuta is almost a year old.
The beginning of the conflict
One evening after a concert, Minho is scrolling through social media and notices a comment from an anonymous account under his post. Attached is a clear photo of Jisung on a playground, carefully holding one-year-old Yuta.
The caption under the photo reads:
"Look how much Yuta resembles you. Don't you think your dream came at a price?"

Minho freezes. Looking at Yuta's features, he shockingly recognizes his own childhood photos. Anger, pain, and a surge of hope knock the ground from under his feet. Minho drops everything and rushes to Jisung's old address.
