I think it was because Sunghoon was close only to Jay and Heeseung when they were new and they knew each other also so since Jay was in underground for some time Sunghoon was attached to Heeseung as he was an introvert and had problems to speak with new people and you can't really make a strong bond quickly especially if you are shy and introvert
He made bond with them pretty fine, especially with Jake and honestly if you watch Iland, it's Heeseung who keeps on picking Sunghoon to be on the same team
I'm re-watching I-land and I'm realizing just how much time Sunghoon spends around the people he likes and is close to, like comfort people (ex: Jake, Heeseung). They don't do anything in particular together, just kinda exist in the same space, and I think it's really sweet. I wish they showed some more downtime/bonding time between contestants b/c it seems like Sunghoon and Heeseung were a lot closer during the show than what was displayed to the audience, and I'm sure there were other pairs that were as well
@@Whoisnabira I just watched it on youtube on Enhypen ❤ Engene's channel ( www.youtube.com/@enhypenengene2188 ) Many episodes are broken up into segments of about 8-30 min but it's not really bothersome because that's about where ad breaks would normally be anyway Everything is typically high quality except for the actual performances so I usually watched those separately on Mnet's channel ( www.youtube.com/@Mnet ) and then skipped them within the actual episode Hope that helps! :]
I usually does not really care about the mbti personality test, but its clear that Heesung as an INFJ trust Sunghoon thats an ISTJ. Since ISTJs said to be concern about INFJs feelings
