Only read this chapter just now after all this time.
Where have I been?!?!
And there goes the plot machine tools in action (again).
Not I was complaining though. ( ͡° ͜ʖ ͡°)
At first I also thought that their soul/consciousness got switched.
But it looks like Mari got a copy Isao's consciousness.
So where is the Mari's soul or consciousness?
Or was Mari (inside Isao's body) lying?
