Well, this is somewhat fresh, in that MC suidical because he didn't want to have regretted not because of some cliche failure.
I mean Japanese MC are all suidical this day, bad grade suicide, tired of work suicide, game data deleted suicide, got bully suicide, I mean dude seriously don't you think it's a waste to die just like that? Sure all MC end up reincarnating which is good, but no way in hell this is happening in reality, sometimes I think those MC got a screw loose or something.
