It helps me to write out my story ideas, and especially to tell them to my friends X) so this is what I'm thinking for the IMFACT/Rookie story

It's summer school/camp

Astro are the optimistic freshmen/sophomore students

IMFACT are the troublesome upperclassmen who tease them and try to break them, but they're actually jealous because they are jealous that these kids are so innocent and happy

Jinam and Win of INX are also upperclassmen, but they are more caring towards Astro, and more mature

The rest of INX and also KNK and MASC are like the counselors and TMRAs.

I am still unsure of who the lead should be. Someone from IMFACT of course. I'm thinking Sang, Taeho, and Ungjae.

Tell me your thoughts? Thanks.
