MO GUANG LIN wasn't sure why that was the first thing he thought the moment he saw the young man. His brain was still trying to piece the reasoning why he suddenly had that thought. It took a few seconds before he finally pieced it all together. It's quite easy once he found the most vital piece of information – that all of this started after the incident between Mo Jian and Yu Jiao.
Logically speaking, a family like the Luo family that's already at the top of S City's upper society, there's no need for them to get involved between the disagreement of two teenage girls. But they did. And Mo Guang Lin easily figured out the reason why.
Because Yu Jiao happened to befriend the second young master of the Luo family.

Ah Jin seeing YanYan's grin: [Crap. It's that smile again, should I just hide?]

Ah Jin felt threatened and shook his head: No where.
YanYan smiled: Good. Now, let's go.
