Alright, Single’s Inferno detectives, grab your magnifying glasses and a snack because we’re about to deep-dive into some of the hottest couple rumors from Season 4. If you thought the drama on the island was wild, wait until you see what’s been happening off-screen.

1. Sian & Junseo: The Main Characters of Our Hearts? ❤️‍🔥

After the behind-the-scenes tea, we now know that the bed scene between Si-an and Junseo wasn’t scripted at all – though Junseo had to clear the air by saying, “What you thought unfortunately did not happen.” So yeah, we know they definitely had some on-screen chemistry, but the real question is… are they actually a couple IRL? 👀

If we had a dollar for every time Sian and Junseo got a little too close post-show, we could probably afford a first-class ticket to Paradise Island ourselves.

Exhibit A: Lee Si An and Yuk Jun Seo are always standing suspiciously close in group photos. The Sweet Home heartthrob even made a heart pose and carried her bag, boyfriend-coded behavior? We think yes.

Exhibit B: They went on a double date with Hyejin and Jonghoon after the show. But the real tea? Junseo was spotted holding onto a photo strip, and while it wasn’t super clear, fans suspect it was a photobooth snap of him and Sian – complete with a possible kiss moment.

Exhibit C: In his post-show appreciation post, Junseo led with a cozy pic of him and Sian. The only other images he shared? Group shots and a handwritten letter to fans – no solo pics with anyone else. Prioritizing Sian like this? Yeah, he’s definitely making a statement.

Conclusion? Either they’re dating, or they deserve an Oscar for this performance.

2. Hyejin & Jong Hoon: The Double Date Theory 👀

Now, if Sian and Junseo are a thing, we have to talk about their possible partner-in-crime couple: Hyejin and Jong Hoon.

Remember that double date? Out of everyone, these four just happened to meet up? A little too convenient, don’t you think?

Hyejin and Jong Hoon keep things low-key, but that’s exactly why people are watching them so closely. The quiet couples always end up surprising us the most.

Are they a thing? Not confirmed, but they’re definitely not making it easy to deny.

3. Dongho & Arin: That One Suspiciously Perfect Interaction 🤨

This one’s subtle, but hear us out.

During a conversation, Arin made a comment about how men should learn from Theo (aka the ultimate green flag), and Dongho immediately responded, “Yes, we will.”

Um… we?! Who is we, Dongho?! Are you speaking for yourself, or are you casually including yourself and Arin as a unit? Because that sounded very boyfriend-coded.

Does this mean they’re dating? Not necessarily. But does it mean Dongho is very aware of what Arin likes? Yes. And that’s suspicious.

Final Verdict: Who’s Most Likely to Be Dating IRL?

🔥 Sian & Junseo: 90% – Too many hints to ignore. We’re one soft-launch IG post away from confirmation.

🔥 Hyejin & Jong Hoon: 75% – The double date is a strong clue, but they’re keeping it lowkey.

🔥 Dongho & Arin: 50% – There’s potential, but we need more receipts before calling it.
