Different world [continuation]

Girl has the magical ability to see a persons memories with a kiss. After being cheated on, she meets a prince who time travelled (?) and who now has no memories. Of course they play the game with him wanting his memories back and both falling in love.

Very funny, refreshing and new take on heroes. A guy used to be the strongest hero when the earth was invaded, but now just lazes about. The new heroes have become like idols and are strictly managed. A newbie finds the mc and wants to drag him back into being a hero.
