The next morning

As usual, Sol A woke up in a very excited mood. She got ready quickly and stood in front of her dorm waiting for Professor Yang. But after ten minutes had passed, he still hadn’t arrived, so she called him.
“Yongboseyo!”
“Are you on your way?”
“Yongboseyo?”

Suddenly, a female voice answered. Sol A was shocked.
“Is Professor Yang there?”
“He’s in the shower. Do you need something?”
“Aniyo”

Sol A hung up and went back into her dorm. The smile on her face slowly disappeared when she realized there was another woman with her boyfriend. She felt not only jealous, but also very sad.

After finishing his shower, Professor Yang came out and saw Han Joo inside his house.
“How did you get in here?”
“I unlocked the password”
“How did you know it?”
“Didn’t you only set one code?”
“So why are you here?”
“I came to have a meal with you. Is your wound healed yet?”
“Not yet, but I already have plans today. I can’t eat with you”
“Missing one appointment won’t matter”

With that, she grabbed his arm and pulled him along. He had forgotten his phone, so he didn’t call Sol A. Han Joo took him to a sandwich shop near campus. While eating, Professor Yang worried whether Sol A had eaten breakfast or not. He didn’t know that she was standing outside the door, watching them. Seeing the two of them together, Sol A didn’t know what to do. She ran back to school, went up to the rooftop, and sat down, lost in thought. Maybe Professor Yang was right, there were too many girls around him, so what happened today was unavoidable. She knew that, yet she still couldn’t stop herself from feeling this way.

After eating, it was time for class. Professor Yang returned to campus to start his lecture. When he entered, he noticed Sol A looked unhappy. But since it was school, he didn’t know what to do. While teaching, he saw her not paying attention, so he scolded her.
“Kang Sol A!!!”
“Nae?”
“If you don’t want to study, then leave the classroom”
“Aniyo”

Her mood, already sad, only grew worse. A thought suddenly crossed her mind: Does he not love me anymore? Is he just playing with my feelings? The more she thought about it, the sadder she felt.

After class, Sol A went straight back to her dorm without even glancing at Professor Yang, ignoring him completely. Knowing she was upset, he tried calling her when he got home, but she didn’t pick up. He drove to her dorm.
“Ye Sul, have you seen Sol A?”
“No, I haven’t. Why, is something wrong?”
“I just need to ask her something, but she’s not answering my calls”
“When I came back, she looked really sad. Maybe she just went somewhere nearby”

Not finding her, he drove back home. The whole day, he couldn’t stop worrying about her, not knowing where she had gone, especially since she wouldn’t answer her phone.

Meanwhile, Sol A was in Busan, the same place he had taken her before. This time, she went to the spot where they had once sat together and then to the tteokbokki shop they had eaten at.
“One order of tteokbokki, please”
“You’re the girl who came here before with your boyfriend, right?”
“Nae”
“Where is he? Didn’t he come with you today?”
“He’s busy” Sol A forced a smile as she replied.

After buying the food, she went to the beach to eat. The weather was beautiful and sunny, but her mood didn’t improve. Sitting there in silence, the sound of the waves gave her a little comfort.

Professor Yang suspected she might have gone back to the beach, so he drove all the way from Seoul to Busan. On the way, he tried calling her, but her phone was turned off.

When he arrived, he rushed out of the car and ran toward the beach to look for her. Passing by the tteokbokki shop, the owner called out to him.
“Yaaaaa”
“Nae?”
“Why did you let your girlfriend come here alone?”
“She was just here?”
“Nae, she just bought tteokbokki. That girl looked really sad, you should go find her”
“Nae, kamsahamnida”

He ran to the beach and found Sol A sitting in the exact spot they had once shared. He quietly walked over and sat beside her.
“Waegudae?”

Hearing his voice, Sol A turned her head. Suddenly, her voice caught in her throat, and she couldn’t speak. Tears just began to fall. She looked at him, and the tears wouldn’t stop. Without asking anything, he gently wiped them away and pulled her into his arms.
“I’m sorry. I’m really sorry. Don’t be sad anymore. It’s my fault”

The more he spoke, the harder Sol A cried. All the feelings she had been holding back since morning suddenly poured out.
“Please don’t cry. I’m sorry”
“Why did you treat me like that?” she asked through her tears.
“I’m sorry. It’s all my fault. I’m sorry for not having breakfast with you. I’m sorry for scolding you earlier. I’m sorry for leaving you alone. Please don’t cry anymore”

She kept crying, soaking his shirt with her tears. All the grievances she had endured finally burst out.

To be continued.
