Huh i guess everyone is thinking incest. But that wouldve been the case right at the moment if Kagami introduced Shinobu's mom as a relative. But she didnt.
That makes it pretty obvious that "aunt" is probably just a caretaker or guarding. Anywhoo, time for me to find out 🤣
Edit: i do realize from the previous colored page that they had the same color of eyes. Faaaak. Okay lemme move on to the next chapter omg.
