Who flirts with the two of them?

Gaia could do nothing but cry and cry all the pain she was feeling. That will be the last time she has a desire for Kevin. She will stop herself from doing the thing she shouldn't do. 

Sunlight caused Kevin to wake up. He got up when he saw soup on the side table with a note.

"Mr. Kevin, drink this, someone told me that it loosens the hangover. Good morning, I'll just go out and take some fresh air, take your medicine too," Kevin was holding his head as he remembers he was kissing Gaia. 

"Why did I saw Gaia last night? I guess I'm so drunk,"

Gaia was walking near the shore. The wind is strong as she was walking on the white sand.

Kevin approached the terrace in his room. He looks around and he sees Katy walking alone. Katy was playing with the water as she was smiling. Kevin didn't know why he was smiling as he stared at the woman he didn't know very well.
