Unlucky is also a good bad trait. Just hate to waste the clovers to compensate for unlucky. Since I am the min-maxing kind of guy, I'd hate having to compensate for stepping in dog-shit, while beach and forest events are much easier to deal with. I never swim at the beach, so shark encounters are non-existent.
Usually MC's birthday is roughly 60 days away from the starting point, so that is a lot of compensating that potentially needs to be done. Since you have no real reason to be meeting Shark-chan or Bear-kun, I prefer the animals hate me trait.
