The stalker is unjustifiable as a character, and I feel bad for the poor 'bully'. They are both fucked up but it is fucked up as in 'this guy should reflect' and 'this guy needs to be detained and get therapy'
It's not cute, whatever the stalker is doing.
That being said, I will still read this because I am curious even though I know it will only have one possible ending (them being tgthr, somehow)
