Hit Your Heart (HuH) is the second extended play by South Korean girl group 4Minute.

Promotions for the mini-album in South Korea continued with "I My Me Mine", which later received a single release in Japan.

The music video for "HuH" starts with their song "Who's Next" which features label mates Beast introducing 4minute, while 4minute walks in a dark background.

Member Jeon Ji-yoon sings outside of an apartment, Heo Ga-yoon has a couch as her background, Nam Ji-hyun sits on a big chair, Kim Hyuna has a motorcycle on her background, and Kwon So-hyun is in a cap store.

By the end of the song the scene shifts between the desert, the parking lot, and their solo concepts.
