The Summer I Turned Pretty Season 3: If there’s one thing The Summer I Turned Pretty fans have learnt by now, it’s that nothing is ever dropped by accident. Not the dialogue, not the flowers, not even a glance. So when Prime Video released a new poster for Season 3, right after the emotional rollercoaster of episode 7, fans noticed a major hint that almost confirms Belly and Conrad endgame despite her engagement to Jeremiah.

The Summer I Turned Pretty season 3 episode 7: Conrad’s heartbreaking confession

Episode 7 hit hard. Tensions were building for weeks, but this time, he finally delivered. Conrad, finally pushing past his usual walls, admits what everyone has suspected for ages: he’s still in love with Belly. In a raw scene, he tells her how hard it’s been to watch her get ready to marry his brother. How he never really stopped loving her.

But Belly? She’s conflicted. She tells him, “We were never anything.” She’s chosen Jeremiah. She walks away, tears streaming down her face, leaving Conrad completely shattered.

And yet, there’s a feeling that it’s not really over—not for them. Not yet.

The teaser poster that sparked all the theories

Not long after the episode aired, Prime Video dropped a new promo poster. At first glance, it looks like a simple shot from what seems like a wedding. Belly is standing in the middle, and both Jeremiah and Conrad are behind her, with all three of them sporting mysterious expressions.

But it’s Belly’s hands that fans couldn’t stop talking about. And although the poster tries to hide it with the words, “final season,” it leaves just enough space for fans to piece everything together. She’s subtly making the shape of an infinity symbol, and long-time viewers know exactly what that means.

In both the books and the show, the infinity sign has always been connected to her and Conrad. He once made her birthday pancakes in the shape of an infinity symbol. He gave her an infinity necklace. It’s their thing. Their promise. That no matter what — time, distance, mistakes — their connection would always be there.

The way she’s holding that sign now? It doesn’t feel like a coincidence. It feels like foreshadowing.

The clues that go deeper than you’d think

This isn’t the first time this season has dropped subtle hints. In an earlier episode, there’s a crossword puzzle that reads “P.S. I ___ Love You.” The answer is “still”. When fans looked closely, the puzzle formed the shape of an infinity loop.

Then there’s the clock shown in episode 7. It points to 3:05 (3 + 5 = 8), and later 5:20 (5 + 2 = 7). These numbers seem random — until fans linked them to episode numbers and the infinity sign itself (8 on its side). Basically, the show is whispering to us: infinity matters.

Reddit and TikTok theories are running wild, and almost all of them land in the same place — Belly might be marrying someone, but it might not be Jeremiah. This could be her wedding… to Conrad.

When does the next episode drop?

If you’re counting down the days, episode 8 of Season 3 is set to drop on Wednesday, August 27, 2025. That gives us exactly one week to sit with Conrad’s confession, Belly’s tears, and that very suspiciously timed poster.

The final season of The Summer I Turned Pretty began on July 16 with two episodes, and it’s been releasing new ones weekly every Wednesday. The finale is expected to hit on September 17, 2025, and it’s already looking like it’s going to break hearts in the best possible way.

Why the infinity symbol means so much

From the very beginning, Belly and Conrad’s relationship has been more than just a teen summer romance. It’s been messy, emotional, and often painful—but it’s also always felt like destiny. The infinity symbol has followed them everywhere. From childhood birthdays to letters to whispered promises, it represents something bigger: forever.

Even when Belly is with Jeremiah, she’s hiding that necklace. Even when she says she’s moved on, the symbol keeps showing up. As if her heart is quietly reminding her of the truth.

And now, with the poster showing her making that sign with her hands—right after Conrad’s biggest moment of vulnerability—it feels like the show is pointing us toward an ending we’ve been hoping for all along.

So, are Belly and Conrad getting married?

Nothing has been confirmed officially, but the clues are adding up. Between the emotional weight of episode 7 that revealed the crack in here and Jeremiah’s relationship, the history of the infinity symbol, and the poster’s subtle messaging, fans are convinced that the finale might not just be a wedding — it might be their wedding.

Whatever happens, this feels like the beginning of something full circle. A love that has stretched across summers, heartbreaks, and family bonds. And if the infinity symbol is really what we think it is… this love story might just end exactly where it was always meant to.
