1-Blood,sweat and tears

Jihyo is best friends with Chanyeol and their dream ever since they were kids was to make a business together and here they are but,something isn't right Jihyo works so hard she doesn't know what fun is and Chanyeol begins to feel lonely unable to express his feelings to her.

Jungkook is the younger brother who has done what he thought may never have been accomplished and opened up his heart to a girl but just like he predicted she stomped in it and smashed it into a million pieces; can he ever love again? Nayeon is also Jihyo's best friend confident,beautiful and loved by everyone in the work place but deep down she has low self esteem and doesn't see herself for what she's worth.
