Often, a cliche childhood friend onee-san manga has repetitive tropes like the childhood promise that always comes true or the overused protective older sister stereotype. Also, the story might lack depth in character motivations and have very straightforward story arcs.
You can start by introducing the characters. Describe Onee San's personality traits, like whether she's kind, strict or adventurous. For the reader, think about their goals and dreams. Then, come up with an inciting incident that brings them together, such as the reader getting lost and Onee San helping them. This will set the story in motion.
Often, such stories have predictable plotlines like the childhood friend protecting the protagonist or having a secret crush. The characters might follow stereotypes too.

The Mila Mountain Tunnel was a key control project of the high-grade highway of the Lalin section of the Sichuan-Tibet line. It was a double-track separated tunnel with a total length of 5720 meters and was constructed according to the standard of two-way four-lane high-grade highway. The tunnel was located in a cold and anoxia-deficient area at an altitude of 4750 meters. The construction faced difficulties such as low oxygen content and limited working hours. The tunnel was jointly built by the Second Bureau and the 12th Bureau of the China Railway Group. It took more than four years to build and was recently opened to traffic.
