I know you're looking for a yaoi manga, but maybe this one? http://www.mangago.zone/read-manga/gunjou_no_subete/
Ok so this isnt bl, its straight, but it matches yout description and is one of the best i have read. Its called: our relationship is....
I don't mind shonen ai! Its just when it's straight the surrounding don't really joke when they say the two should get together and I like the "we have a secret" vibe (>~<)
I tried reading it but it was really boring so I dropped it... You recommend I give it another try?
I had read it but thank you anyways(づ￣ ³￣)づ
I see, i liked the concept of long term besties becoming lovers and that one was my first so maybe thats why i liked it. I recommend you try it again but if it still gets boring then you could drop it heh ^^
I always like the "really touchy best friends that everyone around jokes that they're like husband and wife but really they're just friends until they become more... *Wink* " yaoi story line, I don't care if it's in school or an office if you can recommend any mangas that fits this description please share them with meヾ(☆▽☆), thank you.
