Would you recommend reading the webtoon. After ep4 I kind of what to know more.
well it's different for everyone. some people are very sensitive and they are letting their emotions to control their actions. he also saw his first love's dead body so this must have traumatised him. i think webtoon is better because they handled the relationships between characters well. also this story has a some sort-of dramatic, or even comedic lines and i think it suits the webtoon-style more.
i'm confused but i think he drank the antidote, so he just threw up because poison is leaving his body. but i'm not sure how will they connect her dying in the past and returning the modern time because it doesn't make sense.
