Indigo sat beside her. Then he opened the bottle of water and brought the lid to his lips. 

Chastity couldn't help but watch at him as he drank his water. She stared at Adam's apple. After half-emptying the mineral water, he wiped the sweat off his forehead with the hem sleeve of his shirt. 

Chastity took out her handkerchief from her pocket and handed it to him. “Here, Indigo.” She smoked. “Uh, don’t worry, it's clean. I haven't used it yet.”

He chuckled before taking the hanky from her. “Thank you, Chastity.”

Chastity watched him as he wiped his sweat. Darn. Even if he's sweaty, he still looked gorgeous and smelled good. He didn’t even look haggard. 

“Hmm, you two still haven't finished?” 

Chastity almost jumped when she heard Sir Mike's voice. Both Indigo and her turned their heads to Sir Mike who was back at the gym. 

The teacher was walking towards them. 

Chastity pursed her lips. “Sir, the gym's too big for us two."

“Alright." Sir Mike nodded as he looked around. "That's enough for the two of you," he said, dismissing them. 

Chastity couldn't help the smile on her face. “Sir, thank you.” She immediately went to him and handed him their forms. 

“Indigo, I'm sorry again. I wasn't able to help you with anything,” she said while they were walking out of the gym. 

 Indigo smiled at her. “It’s okay, Chas. Don't worry about it."

“For me, it's not okay," she answered, looking at him. “I wanted to make it up to you, at least." 

“You bought me water and lent me your hanky. That’s enough for me.” Indigo said. 

Holy cow! Chastity felt like a bunch of butterflies invaded her system. His smile was really something.

“Uh…” Chastity bit her lower lip. She was suddenly lost for words. “I’m sure, you're already starving from the mopping that you did. Come on, I'll treat you."

Indigo shook his head. “No need for that, Chas.” 

Chastity pursed her lips. “Come on, Indigo. Please." She pointed at the convenience store just outside their school. "Just let me buy you some ice cream?”

“Hmm, alright," he said. "Ice cream will do."

Chastity felt like she wanted to jump in glee when Indigo finally agreed. Thank God she was able to restrain herself. 

“What flavor do you want?” she asked Indigo while looking at the ice cream in the freezer of the convenience store. She got a drumstick of vanilla ice cream for herself. 

“Strawberry.” Indigo answered.

"You like strawberries?" she asked in a curious tone. 

Indigo smiled. "Yeah."

She then pursed her lips. “I should call you SB, then."

Indigo's brows furrowed. “SB?”

“Strawberry boy.” she chuckled.

“Strawberry boy, huh?" Indigo raised his brows at her. "Then you’re vanilla girl," he said, smiling. 

Chastity felt like butterflies were flying inside her stomach. Every time Indigo smiles, he becomes more handsome in her eyes. His smile should be illegal.

Aside from ice cream, Chastity also bought some doughnuts for them.

She was about to pay for their order when Indigo suddenly handed her some money. 

 “I’ll pay for the doughnuts, Chastity,” he offered

Her brows furrowed at him. “But this is my treat, right?”

“Hmm, I only agreed to doughnuts, though," Indigo said. The corner of his lips curled up in a smile. “So, let me pay for these doughnuts.”

Instead of arguing with him, she just pursed her lips and shrugged her shoulders. 

 “Fine, strawberry boy.”

Miss Aguas, Chastity's last teacher for that day, was absent in class. That's why she decided to go to the senior building to wait for Indigo. While sitting on the bench, she took out her phone and texted him. 

 Hi, Indigo. I'm already here in front of the senior building. I'll wait for you here.

She didn't expect that she would receive an immediate reply from Indigo since she knew he was still in class. But then only fifteen minutes later, her phone beeped for his text.  

Sorry for keeping you waiting. I’ll be out in a while. 

Just like what he said on his text, she already saw him ten minutes later. Chastity smiled. 

But then her smile suddenly wavered when she noticed a girl walking beside Indigo. The girl was smiling while talking to Indigo. And Indigo was also smiling at the girl. 

    Oh. Is that girl his girlfriend? 

Chastity bit her lower lip. Indigo was good looking and tall. It shouldn't be surprising if he already has a girlfriend. 

    Chastity continued to watch them when Indigo suddenly turned to her direction. He smiled at her. 

But Chastity was unable to smile back at him. 

Indigo turned to the girl he was talking to to say his goodbyes. The girl left Indigo and went back inside the senior building while Indigo started walking towards her. 

Chastity stood up from the bench when Indigo was already in front of her. 

“Hi, Chas. Sorry if you waited for me," he gave her an apologetic smile. 

“It's okay, Indigo. My class just really ended early since one of our teachers is absent today.” 

This time, she was able to finally smile at the guy in front of her. But while they were on their way to the library, Chastity couldn't help but feel occupied with the girl she saw with him. 

“Uh, by the way, Indigo. The girl you were talking to earlier… Is she your girlfriend?" she couldn't help but ask him. 

Indigo's brows furrowed. “Girlfriend?” he asked, looking surprised. "No, Chastity. She's only my classmate."

    “Ah,” Chastity slowly nodded. She couldn't understand while something inside her celebrated with Indigo's answer. 

     “What makes you think she’s my girlfriend?” Indigo suddenly asked. 

    “Huh?” This time, it was Chastity who were surprised by Indigo's question. “Uhm…I just thought she's your girlfriend. You two seem closed. Besides, she's pretty.”

    “Well, you're wrong, because she's not my girlfriend,” Indigo said in a serious tone. But then she noticed the corner of his lips were upturned in a small smile.
