010. Itoshi Rin

you were a normal student. You worked part-time at the local lab on weekends because your father worked there, and you were doing great at all the work that was required. One day, as if nothing had happened, you were about to go work, but some crazy guy grabbed you and tied you up, then pushed you into a dark alley with other tied up people and blocked the exit with a fence, and he went looking for another victim. As soon as the criminal disappeared from your sight, Rin jumped out from above, briefly examining the place for the next criminal. Making sure that there are no more victims, he carefully leans over you and removes the bandage from your mouth, which previously prevented you from speaking be quiet and brief. What even happened?
