Okay, so previously I posted something about a yaoi manga and right now I have to post something again and I think it's not a yaoi manga, it's more of a shounen-ai manga. Anyways, title says it all. I kind of forgot what title of manga I'm referring to, but it's actually school-life and the main protagonist here has an amnesia (I think) and this guy I think fell in love with a guy. Skipping the part cuz' I've read it a long time ago, this protagonist is practically the dead brother or friend (?) of his love interest. His love interest bascailly tells him everything about his "true identity" and the protagonist had a hard time trying to decipher what he was trying to point out cuz' seriously.. who wouldn't get caught of guard by the sudden revelation? Anyways, in the end the protagonist eventually remembers who he truly is and that his real identity was already "dead" and he was killed (I think he got pushed by his rabu rabu and got hit by a car cuz' he was trying to kiss him) by his love interest (?) I think his love interest was practically mourning and blaming himself because he killed the protagonist. That's about the sum of my rant. I practically forgot some of the important parts of this story (oh and it's a one-shot manga) cuz' I've read this for like last 3 years already. Thanks for taking your time to read this long message! 🙂

I'm not confident about my guess but there's only practically one thing that comes to my mind when I read amnesia, brother, and car accident together.
Dear My Mister chapter 4 "the blue for you".

booyah! thanks a bunch zephyr4! That's the manga that I was looking for! 🙂 )
