I am looking for any yaoi manga where at least one of the two protagonist have long straight hair.

Please list any suggestions you know. Thank You

well this topic will be moved to the yaoi/yuri section 😛

and...
Utsushimi no Hana

KanataxYuki will always remain in my heart...
Their love is so profound~!

Just about anything historical.
Notably Kinpeibai Kinden Honoo no Kuchizuke by Mizukami Shin

This thread will probably help.

Which A) I'd suggest reading all forums rules seeing as this was originally posted in the wrong section. All yaoi/yuri related threads go to the yaoi/yuri section of the forums. B) Doing a search before making a new thread helps. Most of the time I find there's already a thread asking what I was looking for, and has a few post on it as well.

Hope the link helps

Yes yes, I know I make longwinded comments, but that's just me >.<
I should proof read my comments more, but I won't...
So keep in mind I'm filled with typos
