Lizzy hasn't been able to promote with the rest of her members from the beginning of their comeback while Nana had hurt herself just last week. Pledis Entertainment�said, "Lizzy and Nana's recoveries are slow, so it looks like they won't be able to promote this week, either."

On Lizzy's status, they said, "She took off her cast and she can walk without crutches, but she still needs compress bandages. She was originally supposed to recover for 2 weeks, but her ligament isn't healing as fast as we thought, so she can't promote yet."

On Nana, they said, "Nana's recovery progression hasn't been that good as well, so she won't be able to promote this week either."

As the girls are planning to promote in Japan starting from August, it looks like neither Nana nor Lizzy may be joining for the official promotions of "First Love". Their label added, "We're only looking to promote in Korea until July, so time-line wise it's impossible to do a follow up song. We're watching them carefully to see if they can stand on the final stage with the others, at least."

Hopefully, they heal soon!
