“What do you want to eat for lunch?”

Jiwoo asked as they left the engineering class.

“Anything.”

Sarang had no appetite.

She had been feeling weak for the past few days because she hadn’t seen Do Han.

It had been three days since they had worked on their date assignment at school.

Over the weekend, she hadn’t been able to have a proper phone conversation as she had visited her parents’ house.

Still, she had thought that she would see Do Han in the “Love and Marriage” class tomorrow, so she tried to endure a little longer, but last night, she received a message from Do Han, saying that he might not be able to attend the class.

He mentioned that he had something to do at home and would call her later, but there had been no further contact from him.

Sarang worried if something bad had happened, but at the same time, she missed Do Han so much.

Even though they had only been apart for three days, it felt like they hadn’t seen each other for three years.

She had thought that being his girlfriend meant she could see him anytime she wanted, but it seemed like they had gone back to the days when she had liked him from afar.

“How about going to the Physical Education cafeteria then? Call Yoon Jae Han.”

“Let’s go somewhere else.”

“Why? It’s close, and the food is good.”

Jiwoo had planned to eat outside today because the engineering cafeteria’s lunch menu wasn’t appealing, but Sarang declined.

“Do Han oppa doesn’t like me meeting Yoon Jae Han.”

“What?”

Jiwoo’s eyes widened as if she had heard something unbelievable.

“Did Do Han oppa get jealous?”

The word “jealousy” didn’t seem to fit Do Han, but Sarang nodded reluctantly.

“Really? Do Han oppa? The notorious Do Han?”

“What’s going on here?”

Jiwoo opened her mouth in disbelief.

Sarang frowned at Jiwoo’s reaction.

“Do Han is not like that. Don’t say that.”

However, even though she defended Do Han, Sarang couldn’t help but feel uncomfortable about her friend’s words.

“Alright, sorry. So, can’t you even have lunch with Yoon Jae Han now?”

“It’s not like that…”

As they left the engineering building and walked down the street, Sarang suddenly stopped and stood still.

“What’s wrong?”

Sarang stared at something with a serious expression, and Jiwoo turned to look at what had caught her attention.

Across the street, Do Han was walking, but he wasn’t alone. He was with Hye Ri.

Jiwoo and Sarang exchanged glances as they couldn’t help but notice that the two didn’t look like typical senior and junior students.

Do Han might not be aware, but Hye Ri seemed to have feelings for him.

Or, if not, she wouldn’t be wearing such a happy expression while looking at Do Han.

Jiwoo gave Sarang a meaningful look.

Sarang was also thinking the same thing. Do Han’s girlfriend, Sarang, was in a difficult situation.

Jiwoo didn’t know what to say, so she just smiled awkwardly.

Sarang took out her phone and made a call.

It was probably Do Han.

As Sarang brought her phone to her ear, Jiwoo watched her with bated breath.

“Please answer,” Jiwoo silently pleaded as Do Han checked his phone.

And then, he put it back in his pocket.

Jiwoo’s heart sank.

Sarang was probably in a complicated situation right now.

Sarang had a worried look on her face as she glanced at Jiwoo.

The recorded message saying that the customer couldn’t answer the phone caused Sarang’s hand, holding her cellphone, to drop weakly.

Her eyes were still fixed on Do Han and Hye Ri.

“Jiwoo.”

“Huh? Uh, yes? Why?”

Jiwoo, who had been lost in thought, answered hastily, surprised.

“That person is Do Han, right?”

“Uh, yeah. It seems like it.”

“And the one next to him is Park Hye Ri.”

“Yeah, that’s right.”

Sarang wanted to deny it, but she couldn’t.

Both Do Han and Hye Ri were people who clearly asserted their presence.

Jiwoo, who confirmed that they were together, felt her heart racing.

Not too long ago, Sarang knew that it was Do Han’s birthday, and she had even made a gift and spent a good time with his friends. What was going on now?

Sarang had hoped that Do Han would call her right away and explain that he had missed her call by mistake, but that didn’t happen.

Meanwhile, Do Han and Hye Ri had disappeared from their view.

“Jiwoo.”

Sarang’s voice calling her again left Jiwoo feeling embarrassed.

She didn’t feel like she could give proper answers to anything Sarang might ask.

“About those two…”

Sarang, who had been hesitating, swallowed her words and took a deep breath.

She wanted to ask Jiwoo if they looked like siblings, but she couldn’t.

It couldn’t be.

I must be overly sensitive.

Sarang made a mental note not to jump to conclusions.

“No, let’s go eat. I’m hungry.”

“Huh? Uh, yeah. Sure. Let’s go quickly.”

Jiwoo hurriedly linked arms with Sarang and walked in the opposite direction of Do Han and Hye Ri.
