Mayday _ ''Though'' MV Reaction

Sorry for only posting this now.
Please tell me in the comments what's the story of the MV, I didn't quite understand what it's about because of the twist at the ending.
Is it about how a person can be though and tenacious to chase after his dreams no matter what circumstances he's in? or is it about how dreams and inspirations can help you live better and be stronger when facing difficulties?
I have many guesses, but I can't be sure because it's a little confusing for me.

"tough" as in "won't give up easily". in the end he received a new magazine- "let's build another one!" the dream lives on~

is tough to go after your dreams but dont give up..

[@火云邪神-y1i]

the child still alive, represent the dream still alive

[@jrrylee100]

in the end, although the rocket(dream) dropped(failed) , the kid is still alive, meaning your dream is still going or even moving on.
and that's why the sound is called "Tough "
BTW, the MV, Beginning of the end by Mayday, has some connect to this video, more simple but also great. Recommend it to you

Thanks for telling me about Beginning of the end, I'm going to react to it next I think.
What you said makes sense.

Your dream is so precious. ✧*｡٩(ˊᗜˋ*)و✧*｡
When growing up and forgetting the original intention,
Don't forget to look back at the little one behind you.
I think the boy is still alive represent the protagonist's dream will not disappear because of the failure. 🥰

Now that you're mentioning it, I think it makes more sense to interpret it like that.
Thanks 😄😄.
