I Don’t Know Which Is Love, Volumes 3 & 4

January 28th, 2026

I Don't Know Which Is Love Volume 3 cover. It shows Maria, a pretty lady with long brown hair wearing lipstick, holding up a phone that shows a surprised looking Mei. I’m Luce, and it’s been a while! I’m back today with a double issue of the Yuri rollercoaster, which contains no actual rollercoaster content. I can be found on the Okazu discord as farfetched. Onwards!

In Volume 1 & Volume 2 we saw Soraike Mei get closer, in various different ways, to her five love interests, and generally be something of a lesbian disaster. In Volume 3 of I Don’t Know Which Is Love, she’s practicing for the play, which involves kissing – having kissed both Karin and Kaoru, she’s confused as to why it felt good both times! Good that there’s a certain psychology professor to help her sort it out… Or just make it more complicated? In Volume 4, the play having gone well, Mei ends up in a situation with a drunk Maria, and meets up with her high school crush who broke her heart. Resolving herself to date Karin, she finds her kissing another girl! Riri wants to see her, so invites her to a photoshoot… but it’s in a swimsuit – will Mei, disaster lesbian extraordinaire, even be able to take photos?

This sold as a romcom – and in many ways it is – but it also feels more like watching a race – who can kiss Mei first? Who can date her first? Karin and Maria are pretty ahead, with Kaoru closer behind. I called it the Yuri rollercoaster in previous reviews, and that’s the feel – not much room to breathe. That said, it’s kind of refreshing for a series not to be ecchi per se but to admit that part of romance for a lot of people is sex. These are college students, it’s not weird for them to feel attracted to each other physically, and no one is shaming them for it, although sometimes they’ll tell themselves off – not in a puritanical way, but in a ‘she’s my professor’ or ‘we’re not even dating’ kind of way.Cover for I Don't Know Which Is Love volume 4. It has Karin, a young woman with short blond hair, looking flirtatious, about to lick Mei's finger.

If you really don’t like Professor Maria being one of Mei’s love interests, probably best to sit this out, since she’s not going away. At least Mei is a college student rather than a high school one, but I understand it might irritate people. Of all the love interests, Riri gets the least to do here, only appearing a few times, although she is cute when she does. She does pop up in Volume 4 in a photo shoot, wherein Mei realises she has a thing for boobs.

At the end of Volume 4, Mei asks Maria for a quiet beach spot so Riri won’t get harassed while they’re at the beach. Maria uses this as an opportunity to get all of Mei’s love interests together, so Mei can choose one. Which sounds like a set up for a final volume, but apparently a sixth volume recently came out in Japan, although there is no date for the fifth one in English. It doesn’t really seem to be gunning for any kind of polyamory ending, but neither is any girl really ‘winning’ right now. Mei certainly can’t make her mind up!

Perhaps an issue with this kind of series is that it either needs to be long or short. How Do We Relationship had the time and (I suspect) the planning to carry out that tangled mess of relationships. Although that was more of a serious tone and the intents are different, I’m not sure the author here has a particular plan in mind. As such, I worry it might end up being a bit more meandering. We will have to see; I still enjoy it, but I’m honestly not sure where it’s heading.

You know, for a series about lesbians, they sure don’t say the word lesbian much. If at all.
