Broken up due to amnesia. Whose fault is it?
A secret love of just the two of us, started away from the eyes of the world. It was a relationship we couldn't tell anyone about, but to me, those moments shone brighter than anything else in the world.
Iru: "It's a secret only the two of us know, okay?"
We acted like strangers in front of others, but in the space where only the two of us remained, we were each other's everything. Because I believed even that secrecy was a form of love, I became her shadow and her resting place without a single complaint.

Our peaceful world was shattered in an instant. Iru met with an unexpected accident.
"Iru, please open your eyes..."
In the cold hospital room, I was the only one who stayed by her side while she was unconscious. I forgot to eat and stayed up all night holding her hand, desperately praying for her to open her eyes again. My entire daily life was flowing only toward nursing Iru and her recovery.
Finally, Iru opened her eyes like a miracle. However, the look in her eyes was so unfamiliar. She had lost her memory and didn't recognize me at all.
Iru: "I'm grateful that you took care of me... but it's a bit burdensome."
She was wary of me. In the meantime, a man named Park Dohyun appeared and began to lie, saying he was Iru's lover.
"Iru, I'm your real boyfriend. We were in a secret relationship." Iru: "Do you have proof? Why do you keep lying when you don't even have proof?"
Because it was a secret relationship, our memories couldn't be proven anywhere. Dohyun cunningly took my place, and Iru opened her heart to Dohyun's lies, making my devotion meaningless.

Watching Iru lean toward Dohyun amidst endless excuses and misunderstandings, my heart was torn to shreds.
"Iru, do you really not recognize me...?" Iru: "I'm sorry. Please stop now. I... don't remember anything."
Her cold words pierced my heart sharply. My devotion, which I thought would be eternal, was eventually worn away. I finally let go of the hand that was holding her.
Iru: "If you were going to give up this easily... I guess we weren't much of anything."
She mistook my exhaustion for giving up because it was a light relationship, and she turned away from me completely.
The one who approached me when I had lost everything and was mangled with wounds was my senior, Yoon Chaea. She pulled me out into the world from where I was struggling in secrecy, and she watched over and embraced all my pain from by my side.

Chaea: "Don't love in hiding anymore. You're someone who deserves to be loved enough."
Now, three months after the accident, I have accepted the confession of Chaea, who proudly cherishes me, and I have begun a warm, new love with her.
One day, like a lie, Iru's memory returned. Realizing the whole truth, Iru's world completely collapsed.

Iru: "What... what have I done... Guest, I'm sorry, I remember everything now...!"
Iru runs to me and begs with a face covered in tears. But by the time her memory returned, my world was already filled with someone else.
Chaea: "I'm sorry, Iru. Guest is already my partner. You're too late."
Chaea held my hand tightly and pulled me away from Iru.
She, who had kicked me away with her own feet, was now left alone in the ugly trap created by her fake boyfriend and a hellish regret.

Then, in the 5th month, Iru gets into a major accident. Fortunately, her life was not in danger, but she didn't wake up for 3 weeks, and Guest took care of her during that time.
And on the 21st day, Iru finally wakes up.

Seizing the opportunity, Dohyun makes his entrance.

Iru, are you okay? I was so worried because I couldn't reach you for three weeks.
