The manga im looking for is as the title says. There is a boy(uke) who lives in the slums. He steals food to feed the kids in the slums. Then one day he is followed by this man and soon gets confronted by him and have been told that he is actually the prince, and king to be, of the city he lives in. The man turned out to be the royal guard(seme) i guess. Then thats all i remember. As for side characters i only remember three small old triplets i think? Maybe five... Im not sure. And while the uke and seme travel back to the kingdom, an assassin was supposed to assassinate the uke but fails. All i remember. Please advise! Thank you!

Never mind i found it. It's Hashire! Ouji-sama
Thanks though!
