It was a great morning for everyone in the living room except for this one certain girl, who's been grumpy since last night. 

"What's wrong with you Sinb? You keep on glaring to Yerin." Sojung, who was obviously oblivious to the happenings last night asked. "What happened? What did I missed?" Everyone knows that Sinb has a roller coaster-like mood, but Sojung finds it weird to see the younger Eunbi's piercing gaze towards the second eldest. But instead of an answer, Sinb just said something under her breath which the eldest cannot decipher.

"Yerin?" She called out, wanting to hear some explanation. Sojung knows that it was nothing serious since Yerin keep on grinning to Sinb.

"I just slept with her girlfriend, Unnie." Yerin said, followed with a loud laughter after Sinb shouted "Shut up, stupid Unnie!" and an equally loud "What?!" from Sojung, who misunderstood the meaning of "slept". Umji's cooking is interrupted after hearing the shout of her girlfriend and their leader in the living room. She walks away from the kitchen while holding a spatula on her right hand and goes to where the commotion is happening. There, she saw her Yerin Unnie, who's almost dying from laughing so hard. Her furious girlfriend who's sending daggers to the latter through her gaze, and her Sojung Unnie with a shocked expression on her face.

"What's happening here?" She asked while walking to Sinb's direction but before she can even approach her, Sojung drag her back to the kitchen. "W-wait, Sojung Unnie" she tried to stop the latter but to no avail.

"Explain." The leader shortly says. "Explain what happened last night" She repeated  after seeing the confuse look on the maknae's face. "The reason of Eunbi's behavior?" Sojung simply nodded and asked her to continue. Umji told her everything and after hearing her explanation, the leader can just shake her head because of how childish Sinb and Yerin is. She even slapped her own forehead at some point in their conversation for misunderstanding what Yerin have said earlier. They were now eating their breakfast and it seems like Sinb is still upset about what happened last night.

SINB'S POV

I can't believe that this stupid Unnie took our quality time last night! We were pretty much busy these days. Our schedules are always packed and sh
