I recommended this a few times here already but it's worth it, this manga is a rare gem and I think it quite fits what you're looking for :D
angsty shit that ends so fucking happily it makes you cry dammit
even better if there's running away involved
and/or low self-esteem (like oh i'm not good enough for this guy or this guy would be happier with a girl)
and/or a suuuuuper sweet seme that blows all the uke's doubts away and loves him forever and ever and EVER
also, NO rape. this is a must because as much as I love hidoku shinaide, the way that relationship started still bugs the shit out of me. i mean if it happened in any other way it would've been one of my favs but alas, they are not, and the second couple is because that tenacious hunk of a seme is just the BEST kind. if you're looking for a manifestation of what i'm looking for, akira and naoya are IT.
thx in advance (≧∀≦)
