while the first half of the manga is predictable over all its really a good manga. at the end where he ask about if he really did take her first time but didn't push for the answer is really good way of showing that his insecurity is still there but he come to terms with it, same with Miki by rejecting the dude's advances despite the difficulties they currently facing, also making MC's friends save him from another death is great to show they have a bigger role rather than just there for character development.
in general a good story and display of character development.
