Apparently some magic forces granted both their wishes. Taemin's body wouldn't survive and Siwon's body would but that's not what they wanted. And since both were hit by trucks but one wanted to die and his body would survive, the other wanted to live but his body wouldn't survive, some magic forces decided," Ok, I'll grant their wishes and switch the souls!! It's a great solution!" And so Taemin went into Siwon's body and lived and Siwon went into Taemin's body and died.
hmm i caught that but i somehow expected more behind it tbh so this left me kinda hanging...
and i feel like that doesn't explain the "how" i just can't stay content knowing that "some magic forces" out of literally nowhere made them switch bodies and that not being further explained i waited for an explanation all along :( but thank you for replying!
ummm there's literally just two things j've been wanting to know from the start
why and especially how tf did they switch bodies
