Luke could also be a book collector or a bibliophile who likes to customize the books he owns. In this case, he has 'cut' a romance novel, perhaps by removing pages he didn't like or by creating a unique binding for it. However, this is a less common interpretation compared to the first two.
Luke and Solo were the two main characters in the Star Wars series. They were all heroes of their youth who had experienced many setbacks and growth. Luke longed to fly and escape from the planet that bound him. He planned to join the Imperial Military Academy. Han Solo also yearned for the life of a pilot, and his path also pointed to the Empire. They all wanted to become pilots and draw their own destiny in the starry sky. Luke's performance was relatively gentle, while Han Solo was a hooligan who was the most important to his survival. They had a complicated relationship in the series, sometimes friends, sometimes enemies. The story of Luke and Solo played an important role in the Star Wars series.
I'm not sure specifically who 'Luke Guldan' is in the 'Tell Me a Story' context without more information. It could be a character, an actor, or someone related to the production in a unique way.
Luke's ticket could be exchanged at the NPC, Erika. Players need to prepare 10 data chips and 5 refined spacetime stones as exchange materials. Each player can use their account to buy 10 tickets per day. The Luke ticket was used to enter the Luke Instance Dungeon. Players could team up with their friends to challenge it and have a chance to obtain high-rare and powerful equipment. The Luke Instance Dungeon could only be played once a day and twice a week. The number of times would reset every Sunday.
His best friend could be a main character. Maybe his friend is like a side - kick in the 'game' of his life, always there to help him with quests or give him advice that's like hints in a game.
Luke might meet other students. Some could be from noble families, others from different planets. There could be a bully - type character who gives Luke a hard time, and also a kind - hearted student who becomes his friend.
Their relationship could develop through mutual support. Since they are having a baby together, they would need to be there for each other. For example, Luke could be there for Jessie during her morning sickness.
One of Luke's main allies could be a new character, let's say a scientist named Dr. Mills. Dr. Mills has been studying the walkers and has some knowledge about their weaknesses. Also, a group of children that Luke stumbles upon could become his allies. They might not seem like much at first, but they have a great sense of the surrounding areas and can help Luke find food and shelter. And of course, there's always the possibility of an animal ally, like a loyal dog that warns Luke of approaching danger.
Luke's friends from the light side could also be important. Characters like Leia, Han Solo, or Chewbacca. Their reactions to Luke's turn and their attempts to bring him back would be significant aspects of the story. There could also be new characters created specifically for this novel, perhaps some Jedi who were thought to be dead but are actually in hiding and oppose Luke's new path.
At first, it could be quite rocky if they find out later in the story. Percy might be angry that Luke has been keeping secrets or has done bad things in the past. But eventually, they would likely grow closer as they realize they are family and start to support each other.
