아 어렵다..설명하기.. 음 ㅠ
하여튼, 여하튼, 어쨌든 are used in the same way, if I were the speaker.
and the meanings are "Whatever", or "Anyway".
For example : 어쨌든 A팀이 경기에서 이겼어! Anyway, Team A won the match. (However the game went.)
* 어차피, 아무튼 are similar to the former ones in some cases.
example: 어차피 넌 숙제를 해야해. You will have to do your homework anyway.
