I knew it, Yoseob is also Gikwang-Hyosung shipper. xD
FortuneTeller: ..the two of you (GK-HS) are a match made in heaven.
Yoseob: *clapping hands* Best couple! ~Date! Date!~
FortuneTeller: Hyosung would have lots of kids, and so will Gikwang.*)
Gikwang: *grabbing Hyosung’s hand* Let’s go now! (LOL marry her first!)
Yoseob: *THUMB UP *APPROVES :))
*)The translation is a bit ambiguous but I think he meant they will have lots of kids together? That’s why GK+HS laughed shyly and the others teased them.
