jinsol's beloved older brother. given their of fourteen years, though, their relationship can, more often than not, look more like that of a father and his son who admires him. insoo has done so much for jinsol and the rest of their siblings, and jinsol appreciates him immensely. ever since jinsol became aware of what a handful he was growing up, he's felt a profound need to make up for his faults, which to him meant not giving insoo any more trouble, and doing everything he asks without question. but, seeing as jinsol is an adult now, insoo tries to encourage his younger brother to think for himself. unfortunately, jinsol thinks every word out if insoo's mouth is golden, so his response, in general, is to say "sure, but what do you think? you know best hyung~"

whether it's because of their similar personalites, the fact that joowon was the one who fed his curiosity about plants, or the fact that joowon has always been just a bit more protective of him, joowon is one of the siblings jinsol feels closest to. he's the one jinsol is most likely consult when he needs advice, as well as the one who talks to jinsol when something's bothering him but he doesn't want to be a burden. they're also the family mediators, though joowon seems to have a lot more success resolving sibling conflicts than jinsol. perhaps it's because joowon is willing to wait and see whether the conflict will end on its own, whereas jinsol just wants to end it as soon as he sees it.

 

in seoul, they frequently go to the gym together, while in nasan, joowon helps jinsol out in the garden.

compared to his other siblings, jinsol is quite distant from hyein, despite being one of the siblings closest to his age. for a long time, he's seen it as his job to pacify hyein whenever she gets fired up, but it rarely works. more often than not, the situation ends with jinsol getting dragged into arguments right along with her, or being snapped at by hyein instead.

 

still, he's always trying to help her, because he loves her just as much as his other siblings. in turn, hyein helps him out in the garden, which he really appreciates. like insoo, hyein is determined to get jinsol to grow a spine rather than just doing whatever insoo and joowon tell him to do, but jinsol, in his own way, is quite stubborn, and would rather just listen to what others have to say than be reactive like she is.

 

(i know she's supposed to be blonde, but this pic fits the aesthetic™)

 

as one of the first people he met after he enlisted, jinsol was quick latch onto yongjoon. growing up with so many siblings, jinsol had never truly felt lonely or left wanting for attention—being such an attention-seeker as a child didn't count in his mind—and finding a companion so soon lifted his spirits. in no time at all, yongjoon became jinsol's closest friend and confidant outside of his family. after they were discharged, yongjoon went back to his hometown for a year, but has since moved to seoul, where he works as a store manager. so now, just like old times, they spend plenty of time together (when yongjoon isn't too busy with work, of course), along with sangeun.

 

personality-wise, there's a certain harmony between them. yongjoon coaxes jinsol out of his shell when he's being particularly meek and passive, while jinsol talks yongjoon down from getting too fired up over the little things.

 

yongjoon promised to take care of jinsol's plants while he's gone, and wants to visit the fam at some point as well! (with sangeun ofc)

though sangeun and jinsol haven't known each other for long, with the amount of time yongjoon spent talking about his girlfriend back home, it certainly felt like jinsol knew her by the time they met in person.

 

their personalities aren't similar, exactly, but rather two different interpretations of what it means to be a kind and generous person. sangeun's is more of a hidden kindness, in that while she can be a bit set in her ways, she ultimately wants to be helpful and kind to others. so, as well as being her friend, jinsol really admires her resolve.

seeing as she and yongjoon got married just before jinsol left for the summer, the couple won't be in nasan right away, but jinsol looks forward to seeing them as soon as possible.
