Suyo Webtoon-ui Na Kang-Rim

Na Kang-Rim is a high school student who generally likes webtoons. One day, he experiences something bizarre: the female main character from a webtoon he often reads appeared before him.

The incidents that happened in the webtoon started happening in the real world too, but the problem is that there is no hero to save her this time! So Kang-Rim decides to become the hero and save her.
