"Let's go on a date with me". It's not an asking or request. It is more close to suggesting in a very informal way. It is so informal and almost rude that it is similar to say like "Let's go hang out" . The difference is that he is suggesting to you to go on a date with him

I think he is asking if you want to date him, or go out on a date with him. I am not sure which one. I am only a beginner in Korean though. 그럼 = Then (?) 저랑 = with me (?) 데이트 = date 고 = ?

İs he asking to be your date or sth? "then be my date sth "?

Date with me,please.
