You can say "네가 정말 자랑스러워." in an informal way.^^' \^o^/

andrewkim7878 Thank you for the extra information. I can read hangul and I know a little bit of the structure in korean but I still need to learn a lot of vocabulary and practice ^^ sorry for the late reply but I really appreciate the help.

Anita, I hope you can read Korean characters but just in case I am adding some additional tips for reading it. 나는 당신이 자랑스러워요. (Na Neun Dang Shin Yee Ja Rang Seu Reo Weo Yo.) When it comes to reading, Korean language is very different from English. It means that you should pronounce each word clearly. You should not omit any parts when reading and speaking. It might be difficult for foreigners who study Korean first. 나는 당신이 자랑스러워요. Na=I, Dang Shin=You, Ja Rang=Pride - Since the structure of Korean language is different from English, I can't translate each word into English word. But I hope you get the meaning and understand it.
