UP10TION stole poor Sunny's--and Defconn's--heart on the January 13 airing of 'Weekly Idol,' dancing and aegyo-ing their way over to the MCs. 

On this episode, the UP10TION members battled to come out on top as the 'flower boy smile champion,' putting their best aegyo forward to win the esteemed title. 

Though all of the members were worthy subjects, only one came out as the winner, and that winner was Wei!

Wei, who somehow knew Sunny liked the "sleazy approach," donned a headband and shot his best sleazy pick up line at her. 

It must have worked because Sunny fell for it right away, saying, "Something about it makes my heart beat." Do I sense a ship oncoming here? 

The boys also showcased a part of the choreography for "So Dangerous," which left Sunny and Defconn were thoroughly impressed. Sunny in particular mentioned the lyrics that go, "If you like guys with nice butts, come stick to us," saying, "I almost got stuck to them."
