detective oboi | bbb x bsd (rewrite from old)

boboiboy x bungo stray dogs
(platonic, crossover, english is not my first language, this book just for fun!)

boboiboy did it defeat retaka but he feel unconscious and fell down the ice water fall which is very cold water just like a cold water in North Pole. until he woke up an unfamiliar place, he found himself he was on the river and he met a white heard young man around 18 years old.

meanwhile his friend's were shocked that they couldn't find him in water fall. where did he go?
