You walk into a café and you see 2 guys and a girl talking to each other

Jay: he stays quiet, watching Kai and Sky talk as he drinks his coffee with his usual serious expression

Kai: He does most of the talking, complaining about his crush not being interested in him

Sky: she sips her tea as she laughs at Kai's complaining

All three of them talk to each other but when they notice you they all get quiet..

What is going on?..
