Regarding this Star Shower event

I couldn't get the tree on the first day, so I tried hard using Dona to get within the top 200 by 10 PM. But when I checked around 11:50 PM, my rank was dropping rapidly. In a fit of desperation, I poured more Dona in and ended up at 57th place lol I regret spending too much, but I've decided not to regret it ٩(ᐛ )و
