Hey! I dunno if it will help much but there are indeed quite a number of Korean prepositions haha. But because of the language structure of the Korean language, these prepositions are often placed after the subjects in sentences. For example using the sentences you provided, This gift/present is for you : 이 선물이 당신에게 줄게요 (I will give you this present) I made it for you : 이것은 당신을 위해 만들었어요 Thanks for helping me : 도와줬어서 감사합니다 And yes you are right when you identified -에게 as the preposition of 아름다운 그대에게. So I'm pretty sure you also understand that Korean prepositions often come after subjects in most sentences ^^
