Can I buy a diamond ring from your credit card?

Suho and Chen took Shin Wu to Chen's private apartment. It was almost mid-night when the three were sitting in the balcony with drinks and discussing something. 

''We can discuss all this in living room or in study room as well. Why are we sitting in this chilly cold wind?'' Suho asked while rubbing his hands.

Chen poured him another glass of drink and said, ''Here, drink it and you will feel warm''.

''How do we talk with Rang? We have to convince him to join hands with us''. Shin Wu said while taking a sip of wine from his glass.

''I think let's go inside and think about it because it's starting to rain''. Chen said while getting up. The other two also hot up and picked up the bottles and glasses from the table and went inside.
