It all started with a simple eye contact.

Park Sandara was just like any other students in that university who was studying for business but apparently loved to stick to her twin brother, Park Chanyeol who chose music for his course because she did not really had friends. Since Chanyeol spent a lot of time in his class with his friends and there was a lot of interesting instruments in that room, she always come there after her class so that she could be with her twin. Sandara did not care if their department were miles away from each other, she would endure it as long as she could be close to her twin.

Her constant visit actually drew her twin's senior attention, Kwon Jiyong, who Sandara never notice despite her being there almost everyday.

Until her eyes finally settled on him when he suddenly sang a song when she was playing one of the guitars there.

She was not aware that they were staring at each other until he finally finished singing the song.

Since that moment, she knew she was drowning.

His eyes were a sea, but she did not mind if she keeps drowning in there.
