I read this manga before but I really can't seem to find it. It's about this boy who is is homeless that got picked up by a rich noble kid then works as his butler. He then gets fired by the boss manager because of something he did,but he still goes to his master's house to give him hot chocolate because he misses him and loves him ☹
