The "energy cost for teleportation" scaling with mass is smart, too. It’s not just a cheat code to carry a whole spacesuit. He has to optimize his gear for minimal weight and maximum protection. This adds a resource management mini-game to the main story. Each trip is a viable experiment, not a guaranteed success. It makes his every action feel deliberate. It avoids the common pitfall of a golden finger that just solves all the character's problems effortlessly.
I really like the secondary characters being given distinct quirks. Bian XiangYang is the cowardly brave friend; Cheng (Xie’s friend) is the playboy wingman; Xie WeiAn is the pathetic pervy uncle; Director Liu lost weight working on the case. Even if they only appear briefly, they feel like they exist beyond Lin and Xie’s story. That’s a sign of good world-building even in a romance-forward narrative.
The system grind is real. Collecting stones for virtual coins is slow and feels authentic. She isn’t instantly OP. She has to work her fingers to the bone in the heat for a few coins. It makes the eventual payoff of getting the 50 coins feel really important.
