Kang Hyo Jae and Park Minyoung were normal college students going about their business in Seoul University. College life was amazing; parties every weekend, new people to meet, and new thinks to learn every day! All the while they should keep up their studies!

But what happens when 6 boys literally come knocking at their door asking for their help?

How about when they're threatened?

And what about when the boys are actually aliens trying to take over planet Earth?

Kang Hyo Jae:

A first time freshman, Hyo Jae studies Business Administration with a minor in Environmental Science. She hopes to become a resort CEO and administrator. She's usually quiet and introverted, but it's a different case when she's with Minyoung and her best friend Jay Park. However, when she’s in a comfortable environment, she would be a little more open; making her one of the most amiable students on campus.  But because of her difficult past, she has a hard time trusting people and letting them know what she’s going through.

Park Minyoung:

A Junior in college, Minyoung studies Medicine and minors in Biology. Minyoung's life-long dream was to be a vet for her local town since there isn't one anywhere near them. She's usually self-conscious about her appearance, so she ensures that she's wearing the right clothes. Still, many students are baffled because she’s considered one of the most gorgeous girls on campus. She lives with Hyo Jae off campus and makes sure the younger is safe and healthy.
