I really like manga where MC has some kind of friendship or relationship with someone really different. You know, the kind of relationship where others just freak out when they find out the truth. The other person doesn't really have to be famous or anything, as long as others would never believe that they are friends with each other.

For example:
Onidere (Shy boy is actually going out with the biggest delinquent)
Kingdom (being close friends with the king of the country..wuuut)
Love Lucky (other than the MC being married with an idol, I like how other famous idols just casually speak with him. Would like more of that sort ^^)
Skip Beat (well duh)
TWGOK (is actually with an idol)
Faster than a Kiss (no one's really famous, but I got the same sort of feel from this manga since they are actually married)

Edit: Would like if the series isn't short, so the longer the better

Witchcraft Works maybe? I dunno...

Dance in the Vampire Bund
the mc was friends(More than? ) with the Queen..

~Give time when it's needed~

I've already read/reading Hunter X Hunter, Magi, Kamisama Hajimemashita and Vinland Saga, and I really loved these! Great reccs.
I've kinda dropped Break Blade and Dance in the Vampire Bund, although I might pick up DiVB again.

Aaaaand for the new ones, Witchcraft Works, Black Haze (might wait for more chapters to come out), Uchuu Kyoudai and Detroit Metal City sound sooo good! I'll get right on those now, so thanks

Please keep the recommendations coming ^^

Edit: Found out that Detroit Metal City has been dropped,and no one's picked it up since february
Why must this world be so cruel

Seconding Akagami no Shirayukihime! Shirayuki and Zen's relationship is so sweet~ <3
