From what I've seen in the comments and considering the fact we only have 10 chapters, I can gauge how good it'd be.
I would definitely start this if the 2ML became the ML, and the current ML just disappears and never comes back. If there's two ML and the FL chooses the 2ML, the ML will obviously try to pull some shit that will
A. Help build the plot
B. throw everything into the trash
It's really hard for me to see this as a potential read when I've been let down by other manga with similar plot, who always go down the B path.
Honestly a hit or miss for romance fans, I'll definitely be coming back to this in the future to see how it's gone and update my comment.
