I recently read this manga where, to get out of a love confession from a stalker-girl, the straight protagonist grabs a random stranger and tells the girl he's dating him and that he's gay. [Coincidentally, the guy he grabbed just so happened to be a rumored delinquent, which is adorable] Of course, he then tries to make this guy dump him by doing stupid things, like making terrible bento, but he just eats it and pretends it was delicious.

I was wondering if anyone could suggest any other manga that follow this premise? Where the protagonist (can start out straight, but doesn't have to) accidentally asks out a guy out (who can be the unpopular or delinquent character)? It can be either shounen-ai or yaoi.

If you're interested, this is the manga: http://www.mangago.me/read-manga/sorekara_kimi_wo_kangaeru/sa/sa-c003/

Unfortunately I can't think of anything that fits your description but I've just read the story you posted and I had to come back to thank you! It was so cute! >///<

Shishi mo Kobamazu...is kinda similar, I guess. (More like the part in the prequel) and Batsu game (conro) has a similar premise (have only read the first chapter so can't say for sure).

Haha, you're so welcome!!
And ikr? I've read it like 6 times since then. 😕 But I'm really happy you enjoyed it and sorry I took this long to respond.
