My Tsundere Kouhai Has Entered His Heat Cycle — Review

There’s a specific pleasure in watching someone who never lets their guard down lose it completely — and that’s the entire engine of this release. A junior coworker who’s spent every scene keeping you at arm’s length suddenly can’t anymore, and reviewers say the shift is genuinely satisfying to hear happen.

What You’re Getting

Circle AND..!♡ built this around CV 一条ひらめ playing a tsundere werewolf kouhai whose heat cycle strips away his usual defenses. It’s tagged for binaural/dummy-head recording, dirty talk, repeated climax, love-dovey sweetness, coercive/commanding elements, creampie, ear-licking, and beast-ear content — a fairly loaded tag list that signals both tenderness and intensity in the same release. It’s priced at ¥880 and runs as a single, self-contained release rather than a multi-part series. The circle behind it, AND..!♡, appears more than once in this list of standout releases, and this earlier entry in the “kouhai in heat” storyline functions as the origin point for a character who clearly resonated enough with listeners to justify at least one full sequel — worth keeping in mind if you’d rather start a series from its true beginning instead of jumping into a later installment.

Story & Scenario

The setup pairs a classic tsundere dynamic with a werewolf-in-heat premise, and reviewers consistently say the combination works because of the contrast: he’s guarded and prickly at work, then suddenly desperate and unguarded once his heat takes hold. A jealousy subplot involving the heroine’s werewolf ex-boyfriend gets specific credit for giving his usually-hidden feelings somewhere to surface without breaking his tsundere characterization outright — it’s a crack in the armor rather than a full personality swap. Multiple reviewers also point out that the “wolf in heat” premise stays away from growling intimidation, keeping the intensity rooted in need rather than menace, which seems to be a deliberate choice that reviewers appreciate.

That choice matters more than it might seem at first glance. Werewolf and beast-ear content in this genre often leans on animalistic dominance as the whole appeal, but reviewers here describe something closer to the opposite dynamic — a character who’s usually the one holding back, suddenly unable to. The heat-cycle framing becomes less about an external transformation overtaking him and more about a convenient excuse for feelings he already had but would never have admitted to on a normal day at work.

Sound & Voice

一条ひらめ’s performance draws consistent praise for making the character endearing from his very first scared, awkward lines — reviewers describe wanting to comfort him before the story even gets to the heat-cycle content. That vulnerability early on is apparently what makes the later intensity land as passion rather than aggression. If you enjoy performances built on tonal whiplash — composed to desperate, guarded to needy — this is squarely built for that.

Who Will Love This

This is a strong pick if you like tsundere characters whose walls come down through circumstance rather than a slow character arc, and if jealousy-as-vulnerability is a dynamic you enjoy. It’s less suited to listeners who want a sprawling, multi-track story to sink into — a few reviewers who loved the setup specifically wished the release ran longer, noting it’s a single, relatively compact entry compared to genre norms with multiple linked tracks. If pacing and volume matter more to you than concept, that’s worth knowing going in. It also pairs naturally with its sequel for listeners who want to follow the relationship further once this one wraps up, so consider budgeting for both if the setup grabs you rather than treating this as a one-off purchase.

The Verdict

Our score: 4.5/5. With a DLsite average around 4.89 from a large listener base, this is one of the more consistently loved entries in its circle’s catalog, and the reviews read as close to unanimous on what works: the tonal contrast, the jealousy subplot, and the character’s overall endearing quality. The only real friction point — wanting more of it — is a compliment in disguise, so we’re keeping the score high while leaving a little room below DLsite’s own number to reflect that this is a tightly scoped, single-release experience rather than an expansive one.
