Help to find a story

It's a multi-story BL manga
The first one was about a young master (Luke?) who picked up an abandoned child and he served him as his personal butler

There was a scene where they laid in this huge ass bed talking about their future or something

Then when Luke found out they couldn't get married they ran away but they ended up slipping off a cliff and the servant had a scar on his face

Years passed and the servant secretly worked at the mansion thinking the young master hated him but it was only a ploy by the head butler

Thanks!
