Hi there! I'm looking for something quite unusual and possibly nonexistent. Namely, any BL manga where the main protagonist's love interest is not obvious. If you look at the cover and read the description and you still don't know anything about the final lucky guy then it's what I'm looking for. Maybe a story where the main character has a crush on character X, but then supporting character Y becomes a major player or Z is introduced after a a chapter or two and swoops in to claim his victim? I know there's a whole category for love triangles, but it's usually pretty obvious who's the true love interest from the very start. Hell, just looking at the cover is enough to figure that out. I want a story where the guy is a big unknown or doesn't even appear in the beginning. Anyone? 😀

Edit: I made the topic title kinda confusing, as I don't necessarily want a decoy love interest to appear before the true one. In fact, I'm more than fine with just one guy who appears after the premise with no other contestants beside him. The only things that matters is that his choice is not obvious.

LET'S POSITIVE THINKING

You really like making rare requests don't you xD
I can only think of Jigoku Yuki Bus right now (ch. 5-7) 🙂

Off the top of my head:
Unbalance na Netsu was surprising to me
Bokura no Mitsudomoe Sensou- kind of?
This is all that I can think of right now. I will come back when I can think of more. 🙂

Kiss wa Ichinichi Sando Made!?
Gokujou no Koibito
Empty Heart
Lover's Position

"A sword is useless in the hands of a coward."

This is a tough one. I think that as a reader, if the main character doesn't end up with the one the author has led you to expect, you ususally feel cheated.

Hydra fits, I think. Hitomi and Ryuu are the expected couple, but then Taira comes along and they are the couple.

But they don't really end up together.

Second Unbalance na Netsu, I didn't expect that. Also I was afraid Lover's Position wouldn't go the way it did.

When a Man Loves a Man - more of a standard love triangle, but the one I rooted for lost.
