Mina was busy waiting for Chaeyoung to come back . It is already past midnight but there is no sign of chaeyoung . She can only let out a sigh while lying on the couch at their living room . The clock keep on tickling, but there is no sign that chaeyoung will be around that night . The phone that she use to call chaeyoung was held tightly in her hand . Everything seems not right for her when there is no chaeyoung with her because without her , her world is dark , just like the dark night sky above.

" Where are you,chaeyoung ? ". Mina can only mumbles while little by little , her eyes close , close into the dreamland. She hopes when she wakes up tomorrow, chaeyoung will be in her side and hugs her tightly .

Mina feels weird because it is really rare her sister in law didn't go to college with her husband, Jungyeon . Nayeon barged into the house after bowing to Mina, mina turns around and looks at nayeon weirdly.

" Unnie ? what are you doing here ? "

" I am waiting for you to go the college together , how about it ? ".

" Suddenly ? why ...?"

" Well , come on , dress up !! ".

Nayeon pushes Mina into her room so that she can prepare herself to college while nayeon waits for her at the living room . Nayeon was willing to helps chaeyoung to ensure that mina is safe in the way to the college . Chaeyoung keep always keep a secret her whereabout last night , she only texts Nayeon and asking her to brought mina to the college after this .
