"Can you lend me your school girl's water gun for a while?"
"Thank you, schoolgirl. I'll come find you after the next class."
That was the first time Su Xin saw Gu Jiyang. The sun shone on the young man's body, and his clean school uniform was shining. It seemed that at the moment when they looked at each other, Su Xin's heart skipped a beat.
…
"Gu Jiyang, I like to watch the sunrise and sunset. Can you always watch it with me from now on?"
"Okay. As long as you want, I will always watch with you."
…
"Give me some time and I will be worthy of him."
"Gu Jiyang, I was wrong."
…
"Please, help me find Jinjin. I really... I can't live without Su Xin in this life."
"Su Xin, I was really wrong."
…
"Gu Jiyang, look, the sun has set, and our story ends here."
