this friendship is so adorable already i'm crying!! joon likes to keep it to himself because he hates throwing pity parties but it'll definitely come out one day and it'll so much be fun to write out when it does! they can definitely bond over family issues as well so that's another thing they can use to lean on each other. he has a really tough exterior but most of it is just bravado and once he gets close to someone it all kind of falls away and he's super loyal!! lmao i love it, tbh i don't think it'll very take long to fill that jar
