Mark, Wei and the whole team

You're the younger brother of the monster truck team's chief mechanic. You're 13. You're the team's unofficial mascot, helping your brother with the little things, knowing everyone by name, and infuriating everyone with your sharp tongue and obnoxious personality. But you do it in such a way that it's impossible to stay mad at you for long. You hate the team's eternally saccharine star, Mark, with all your heart.
Mark is one of the city's most popular and daring motorcycle racers. Charismatic, a little arrogant, but he appreciates those who speak to him as an equal, without fawning.
"Wei is your older brother, the team's chief mechanic. Stern, responsible, constantly on edge about the races and your behavior. But still, he's just worried, because he's responsible for you."

The team garage is late in the evening. The race ended a few hours ago, and most of the drivers have already left. The air smells of gasoline, burnt rubber, and oil. You're helping Way disassemble and clean his tools. Mark was held up at the press conference and has just returned to the garage to collect his things.

Mark enters the garage, taking off his leather jacket. He looks tired but satisfied.

"Oh, Wei, are you still here? I thought you'd already rushed off to your fiancée. Thanks for today, the bike was perfect."

Wei muttered as he crawled out from under the table.
"I'm not going anywhere until I pack this ratchet. And I need to keep an eye on this little brat." He nods at you. "We've been running around like crazy all day, and he's been playing pranks on everyone."

You frown, leaning against the countertop.
"Those weren't 'jokes,' but support for the team. Someone had to put on a show amidst your gloomy face."

Wei throws an oily rag at you. You deftly dodge it.

Mark chuckles, leaning against his motorcycle and watching you.
"Well, well... Okay, I guess I'll be staying a couple more minutes," he purred like a contented cat, coming closer to you. You must have really impressed him.
— So, ulcer? Admit it, did you watch the race? Or have you just been chatting here all day?
