Summary:
His mom is the first person to know about it. She finds out when Izuku asks why he can't see the red line that connected him to Kacchan in the last picture they're taken. The one where they were about to enter Kindergarten on their first day.

"Red Line?"

"Yeah, Mamma. This," Little Izuku says, raising his pinky finger to her the thing tied to it.

Izuku has been able to see the red strings of fate since birth. It's no surprise that his is connected to Katsuki.
