🎀 What is Sekai-ichi Hatsukoi All About?

Hey there! I’m a writer who absolutely loves BL anime 😊

Have you ever thought:

“I’ve heard of Sekai-ichi Hatsukoi, but where do I even start?”
“There are movies and side couples — it feels a bit complicated…”

Don’t worry! The truth is, Sekai-ichi Hatsukoi has a very simple structure once you know the basics. Whether you’re new to anime or just dipping your toes into the BL world, this series is incredibly easy to follow — and emotionally satisfying.

Set in a publishing company, this heart-tugging love story revolves around ex-lovers reconnecting at work — with all the messy feelings that come with it.

The main couple, Ritsu Onodera (the tsundere editor) and Masamune Takano (his intense ex and now-boss), are absolutely iconic in the BL genre. Their “exes to maybe lovers again?” storyline is a rollercoaster of feels 💘

And the best part?
You’ll also meet supporting couples like Yokozawa and Hatori, who bring their own emotional journeys and drama to the mix. If you’re into character deep-dives and shipping your faves hard — this is your playground.


Next up, I’ll walk you through exactly how to watch the series in the perfect order so you don’t miss a single romantic beat 💞
Let’s fall in love all over again — with the World’s Greatest First Love.

💗 Sekai-ichi Hatsukoi Watch Order Guide (2025 Edition)

If you’re just diving into the world of Sekai-ichi Hatsukoi, welcome to a beautifully emotional BL romance with relatable characters and heart-tugging love stories!

Below is the recommended watch order — which also follows the chronological timeline of the story. Watching in this order ensures the best emotional flow and character development.

📺 Recommended Watch Order Table

OVA②: The Case of Yoshiyuki Hatori
OVA (DVD Specials)2011

🧭 Why This Watch Order?

This order follows both the original release and in-universe timeline, giving you the most natural progression of events. It’s carefully crafted so you:

  • Experience Onodera and Takano’s slow-burn tension in the right pace,
  • Appreciate the build-up of side characters like Yokozawa after meeting them in the main series,
  • Don’t get spoiled! Some later movies contain core reveals that would ruin the impact if watched early.

💡 For example:

“The Proposal Chapter” (2020) contains major emotional payoffs from Ritsu’s arc — watching it too early spoils the bittersweet tension of his indecision in Seasons 1–2.


💬 Personal Notes & Fan Tips

  • 💕 Start with Ritsu’s arc: It sets the tone for the series with office romance, classic miscommunications, and Takano’s sharp tongue that fans adore.
  • 🎬 The Yokozawa movie shifts focus but gives deep insight into his heartbreak and healing. Some skip it — but honestly, it hits differently once you’ve seen him suffer in the main series.
  • 💍 The Proposal Chapter is a tear-jerker and should absolutely be saved for last. Trust me — it wraps up the emotional ride perfectly.
  • The OVAs are optional but super fun — like bonus content that gives you more time with your favorite characters. Think of them as dessert after the main course.

✅ Summary

Watching Sekai-ichi Hatsukoi in this order isn’t just “recommended” — it’s how you get the maximum emotional payoff. It respects the story arcs, avoids spoilers, and keeps the romantic tension deliciously intact.

“Take it slow, just like the characters do — and you’ll love them even more by the end.”
