Haneume Buneun Ipsae

Seol Ipsae likes to keep things simple and clean: relationships never go further than physical, and one night per guy is the standard, and only the best will do. So when he runs into the big, bumbling himbo Jeong Han-Eum, he can’t believe his eyes; at first, it’s because the dude’s such a nerd, but then it’s because this nerd is hiding a big, uh, “secret.” Huge, in fact. Massive. One of the biggest Ipsae has ever seen. Y’know, maybe nerdy boys aren’t so bad after all…
