"You're joking, aren't you?" Yongguk questioned me with a hint of disbelief.

"I assure you, this is not a joke, hyung," I replied, flashing a smile as if it were all just a playful jest.

Yongguk's expression betrayed his confusion as he tried to comprehend the situation. 

"Why do we need to pretend to be in a relationship?" he inquired.

"We are simply using this as a tactic to incite jealousy and potentially stir up feelings in him," Daehyun explained, trying to convince Yongguk to go along with the plan.

Yongguk seemed to grasp the concept, nodding his approval.

"But what if our plan fails?" he pondered, furrowing his brow.

I sighed, realizing the potential consequences of our actions. If our initial plan did not succeed, I had not yet devised a backup plan.

"We can use a Plan B, but I don't really have one yet because I haven't thought about what to do if the initial plan doesn't succeed," Daehyun admitted uncertainly.

"So... is this agreement settled between us?" Daehyun asked, hoping Yongguk had finally agreed to the plan.

Yongguk mulled over the proposition before finally agreeing to the arrangement.

"Agreed," he stated firmly, sealing the deal with a handshake.

With that, the two of them solidified their agreement to move forward with the plan.
