If you're stuck, here's a strategy~~

Instead of blindly boarding the passengers right in front of you, it's important to consider the next passengers to move and the empty seats on the bus. Especially if there are only a few seats left on the bus, don't rush to fill it with one type of passenger. It's better to check which passengers the next bus can take before you move. If you board them incorrectly, the path can get blocked, preventing you from making consecutive moves. If passengers are stacked in multiple rows, don't just look at the front; consider the passengers hidden in the back. Creating moves that clear the blocked passengers first will open up many more options later. In the final stages, even one empty seat is quite important. Instead of filling the bus completely, a stable approach is to leave one or two empty spots to create consecutive matches. Boosters are most effective when used not early on, but when movement is truly blocked.
