#topic markers

        Ok so in Korean you need to use topic markers like 은 and는  which introduce a new topic to the sentence.

 은 is used after a word that ends in a consonant잭선은 음식을 먹어요 (Jackson eats food)

는 is used after a word that ends with a vowel영재는 음식을 먹어요 (Youngjae eats food)

        은 and는can be used to talk about things you have already mentioned

For example: “갓세븐의 잭선이 야생이에요. 그는 또한 섹시해요” (Got7’s Jackson is wild. He is also sexy) lol

Since I had already mentioned him in the first sentence using 이 (a subject marker) you already know who I’m talking about so in the second sentence I’m free to use 는

         Last but not least they can be used to show contrast. for example: some K-Pop fans are talking and Fangirl A says “나는 임재범의 팬이에요”  (I’m Im Jaebum’s fan)

Then Fangirl B who is also a fan of him says “나도 임재범의 팬이에요”  (I’m also Im Jaebum’s fan)

But the Fangirl C comes along and changes everything cuz she’s Yugyeom biased so she says “나는 깅유겸의 팬이에요” (I’m Kim Yugyeom’s fan)

In this situation when fangirl C added 는 instead of 도 she was indicating that there was gonna be a change, that there was a contrast between their preferences and hers
