I dont know if this kind of manga exists but anyway.
Im looking for a manga where the main character can read thoughts, This time I would prefer it to be a romance (It would be fun to read about a character who knows exactly what his/her love interest is thinking^^)
If there isnt any in the romance genre, im fine with others to.

also,I can read Yaoi,yuri and smut, so you guys dont need to hold back

Telepathy + Romance
mind reading + Romance
Psychic Powers + Romance

Of the ones listed there the one that closely matches what you're looking for that I can think of off the top of my head is Honey Bitter

Yubisaki no Koi should fit. (=

Kimi ga Uso o Tsuita for sure

I second Yubisaki no Koi muchly.

And I recommend Tell Me a Lie (a oneshot, but it's nice).
