"What?! Why should I do that?"

"Now you are talking about your status as a boyfriend? You never even thought I was there as your girlfriend. You only looked for me when you need something, I wasn't your puppet" Taeyeon said in an angry voice

"I can't be like this—"

Doyeon heard all the words and she felt she had to stop her sister from fighting with someone that she even didn't know who is he

"U-unnie~" Doyeon called out softly. Taeyeon who was on the phone looked towards the door

"Yes Doyeon, what's wrong?" she smiled

"Ah... hmm... unnie, am I bothering you?"

"No Doyeon, come in" Taeyeon spoke again on the phone "We'll talk again later, my sister needs me, hmmm" she hung up and faced Doyeon

"What's wrong Doyeon?"

"Hmmm, can you help me with this home work? There are some questions I don't understand"

"Sure. Sit here, we will slove this together, okay?"

"Okay" she nodded

After a few minutes, Doyeon came out from Taeyeon's room and went to the twins' room to tell them what she heard in Taeyeon's room, but before she entered the room, she heard the twins' conversation from the front of their room, the door was slightly open so she could hear it.

"So you two already....?" asked Sejeong

"Already what?" Chungha asked, confused

"Hyuk sunbae, your boyfriend" Sejeong's eyebrows moved up and down

"Yah, I told you I have nothing to do with him" Chungha said from her bed, throwing a pillow at Sejeong

"Calm down. Don't get mad if you have nothing to do with him, but if you really have a relationship with him, I'm okay with that. He's good, handsome, smart, perfect for you"

"Yah! Shut up. You better think of Eunwoo than thinking of my love life. I think he likes you" she replied

"Eunwoo? Eyy, he's just a stupid boy who always annoys me"

"Yes, he's sure a stupid boy because he always follow a stupid girl like you, I don't know what happen with his brain that make him to like a girl like you" Chungha laughed

"Yah! I'm not stupid!" Sejeong throws back the pillow that Chungha threw at her "But Chungha, what if we already have a boyfriend. It would be fun if we're doing double date" she imagined it with a smile

"Look at you, you're smiling alone just by imagining it, now you look like an idiot" Chungha laughed loudly

"Yah, Chungha! I'm not an idiot!" Sejeong got up from her bed and messing Chungha's hair

"Yah... Yah... Stop... Not to my hair, you idiot" Chungha returned to attack Sejeong and tickled her twin

"Ahahaha okay, okay, stop.. it tickles" told Sejeong, they laughed with their own act

Doyeon discouraged herself from telling the twins about Taeyeon. When she was about going back to her room, she saw Nayoung just came home

"I'm home" Nayoung said

"Unnie" said Doyeon

"Hi Doyeon, you haven't slept?" Doyeon shook her head, Nayoung threw herself to the sofa and reached for her phone. When Doyeon was about to approach her, Nayoung's phone rang and she immediately picked it up

"Hmmm... I've arrived home. Have you arrived at home?" said Nayoung to someone on the other line of the phone with a sweet ton
