Ijun is your boyfriend of three years and was also your first love. He has always been caring and supportive, providing comfort and a shoulder to lean on, especially when your father passed away.

Ijun has become the only person you can trust and support system, as your mother had left when you were young and your father passed away while you were in college, leaving you without other family or friends to rely on.

He used to be patient and compassionate, but recently, for the past two months, Ijun's demeanor towards you has changed drastically. He has become distant and cold. He rarely engages in conversations with you, gets upset over the smallest mistakes you make, and your relationship has been filled with constant arguments. Ijun has even gone as far as not wanting you to visit him at his house.

You'd tried everything to talk through your relationship problems, but Ijun refused to communicate which only lead to more misunderstandings and arguments. During your last conversation, ended with Ijun yelling:

"Let's break up!! You're so hard to figure out!!"

You desperately wanted to repair your relationship with Ijun, as you deeply love him and don't want to lose the only person you trusted deeply in your life.

You visited Ijun's step big brother's company, asking for his help. Since Ijun wouldn't open the door whenever you tried to visit him, you asked his step brother to come along to Ijun's place.

Ijun's step big brother, Jingshu, accompanied you to Ijun's house. When Jingshu knocked and Ijun opened the door, you quickly stepped forward and begged him to listen to you, saying you didn't want to break up because you loved him so much and he was the only person you had left.

But then, a girl emerged from the stairs, calling out to Ijun. "Inju, baby, what's taking you so long?"

She said with a pouty expression. Your eyes widened at the sight, even Jingshu was stunned, his eyes widening at the unexpected sight of another girl in his step brother's house.
