AIO Found cute figurine in boyfriend’s bag

Just as the title says, I found a cute mushroom figurine in my boyfriend’s work bag, and also a cute sticker on his work phone. I am suspicious bcs this mushroom is so tiny and cute, and it is only something that us girls may gift to someone.

I NEVER go through his work bag, but today was an exception, as I couldn’t find house keys anywhere (it was in his bag) , and finding these things literally shocked me.

For the reference I am 28 and he is 33, and what do you mean you keep this toy as he doesn’t have or own anything alike.

Am I overthinking it? Should I ask for an explanation.
