I've been trying to find this manga forever; it's really starting to bug me. I didn't get a chance to read it at the time; I only saw the description. The seme and uke began as friends, but one night while drunk, the seme forced himself on the uke (very original, right?).

I remember much more of the cover. There was a big height/size difference. The seme was very tall and muscular, and the uke was your typical cute lil thing. They were both wearing urban-style street clothes. I think the seme had blond hair and the uke had reddish/pinkish hair. It's fairly new; I believe it came out within the last five years.

Can anyone ID this? Pretty please?

I thought of Bitter - Kare no Hisoyaka na Seppun, but as I kept reading I that the chances of it being this is getting slim.
Have you tried checking under the Drunk Intercourse tag? (It may help.) Maybe also try the Drunk tag.

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

Argh. I had tried the Drunk tag, but I didn't think of Drunk Intercourse. I just tried it now, but nada.

It wasn't Bitter, although I do like Haruka Minami. ^^ Her semes are a little too delicate for this one. This guy was pretty ripped (not as disproportionately huge as an Asahi Shima seme, but pretty big compared to the uke). They both struck me as somewhat poor; they were dressed in very casual street clothes.

This manga is making fun of me right now. ;n; It feels so close but so far.

try this search:
description contains "drunk" and genre = yaoi

if that fails, maybe try drinking or alcohol or some other keyword. Or shounen ai for the genre.

Tsuyogari, second story: drunk intercourse, petit uke x big seme, blonde and red head...

If not, maybe:
Silence (AKIYAMA Koito)? The drunk part doesn't fit, though.
Fudanshi Baby? The drunk part doesn't fit, again.
Toritsu Mahou Gakuen? Do I need to say? The drunk part doesn't fit, haha.
24 Jikan Eigyouchuu? The hair color fits, but the size doesn't.
Wagamama na Jewel? Again, the hair color fits, but the size doesn't.
Bousou Kareshi? The hair color fits, but both are big.

Those are great tips, fvvjy. Thanks! I'm starting to think it might have been listed under shounen ai at this point (although the plot sounded fairly sexual).

Thanks for all those suggestions dalek! =) It wasn't there, but it's funny you mentioned Silence. When I was re-reading the description of the cover, I was like "This sounds a lot like Silence." They weren't wearing formal clothes, but the hair colors and size difference is very similar.

You can't tell about the size difference on the cover, and they weren't exactly drunk... but is it Kanashii Doubutsu?

Ok, this sounds totally stupid. But is it Gravitation? Probably not, right... I want to find this manga now! haha

Nope, it wasn't Kanashii Doubutsu. Thanks though, tastydish. =)

Hahaha, Gravitation. X) I haven't read that in ages. Nope, it wasn't Gravi.

I'm starting to wonder if the seme wasn't drunk. I'm sure he "forced" himself on the uke according to the description, but I don't know if that's violent rape or "Oh no stop~" rape. I've been searching for "friends" and "forced," but the amount of results that yields is kind of ridiculous. X)

Have you tried the rape tag? If it was the 'no stop!' or even ' no ... stop .... wait ok.. umm no' it probably has a rape tag.

Also if you can define you're delicate and buff couple.
Maybe like he was built like the guy in Kishidou Kurabu and delicate like the one in Bitter - Kare no Hisoyaka na Seppun. (Although you already said it wasn't that delicate.)
If we know what the body sizes were more like it may help jog someone's memory.

Yes yes, I know I make longwinded comments, but that's just me >.<

Yeah, I tried the Rape tag already. =/ I'm thinking it might be untagged. I might search through all the yaoi/shounen ai releases in the past two years. I saw it earlier this year (around January-February), so I'm thinking it's from 2012 or 2011. It probably isn't older than that, or I would have read it already.

They were both standing (the cover was from about waist-up) in a downtown city setting. Their dimensions were similar to Silence (AKIYAMA Koito). The uke looked pretty short and skinny, but I think he was wearing a puffy jacket. The seme's build looked like the guy on the floor in Karada Meate de Warui ka (haven't read it; just judging by the cover). His hairstyle was similar too, actually -- it was spiked back like that. I think he was wearing a t-shirt. The uke was on the left, the seme on the right. I feel like I'm filling out a police report. X)

Bit of a stretch, but Re Set? Uke gets raped by Seme and there's that height difference.

Do you remember anything more from the plot? Do you recall if it's a one-shot or a series?

I know that you already ruled-out Kanashii Doubutsu (as suggested by tastydish), but as of your most recent description, I can't help but bring it up, again. (Sorry.)

I'm not sure if you are looking solely at covers posted on MU, but this was the image originally associated with the manga when only the first chapter (or two?) had been released.

OMG! That's it! That's totally it!! =D Thank you so much, weird1! And kudos to tastydish for calling it out so early!

Wow...seeing it there is so oddly validating. =3 I was beginning to think I had imagined this. Don't know where I got the drunk part, lol.

Thanks again everyone~. =)
