He'd be glued to your side the moment your friend offered you to hang out alone and would try and cover up his jealousy but would fail horribly. He'd be staring at your friend but would quickly look away when he made eye contact. After a while, he'd start to nag you to hurry up. He had been quiet and patient throughout your conversation but was getting tired, and not to mention, jealous.

➳ Seonghwa:
"You look really good."
He wouldn't easily get jealous but he'd still get that slightest bit of jealousy, even if he didn't realise it. He'd just stand back and would give your friend glares and wouldn't really care much if it made him uncomfortable. He just wanted to have a day out with you without an old friend flirting with you. Overall, he wouldn't get that jealous.

➳ Yunho:
"We really should catch up when we get the chance."
He'd get really jealous when your friend had offered you to hang out, especially when he was the one hanging out with you, not your old friend. He'd impatiently wait for your conversation to finish, kicking stones around and sitting down waiting for you. He'd try to cover up his jealousy but wouldn't do a very good job.

➳ Yeosang:
"Just me and you?"
He'd respect that you hadn't met your friend in a long time and would be pretty patient when waiting, but the idea of you and him hanging out together caused jealousy to bubble. He's pretty shy so would still stand back and wait, but deep down he wanted to grab your hand and walk away. He'd still be respectful but he couldn't ignore that jealousy.

➳ San:
"Remember how close we used to be?"
San is clingy as it is so when he heard those words, he'd be all over you, hugging you, resting his arm on your shoulder and leaning against you. He'd try to make your old friend jealous to cover up his own jealousy. He didn't like that you were talking to your friend more than him, especially when you had planned the day just you and San.

➳ Mingi:
"You've changed so much, you look fantastic."
Mingiwouldprobably be behind you, rolling his eyes and sighing, annoyed at how long your conversation had been going on for, and even more so when your old friend began complimenting you. He'd basically be really annoyed and impatient and would make it obvious he was jealous without even realising.

➳ Wooyoung:
"You should visit soon."
He wouldn't hide his jealousy at all. He'd be constantly trying to get your attention, calling out your name, poking your shoulder, pulling on little strands of your hair. He didn't like your old friend one bit, and he really didn't care how much his jealousy was showing.

➳ Jongho:
"I've never forgotten about you."
Jongho, unlike Wooyoung, wouldn't show jealousy at all, and he wouldn't act any differently. He didn't like the way your old friend was talking to you but he respected it and kept his jealousy to himself, not wanting to ruin your meet up with an old friend after a long time. That jealousy was definitely there though.
