Hearts to Hearts Yeon, who participated in the Love Hachuping Special OST

YE-ON 【Love's Hachuping: Legend of the Whale Jewel Special OST Part 2】

An OST featuring Ye-on's pretty voice has been released o(^▽^)o

Since I heard Yuha and Yeon participated in the Hachuping OST, I feel like I should go see Hachuping haha.
