From what i get it's hinted that mc has been disappointed by many of his previous relationships he kind of give up about romance, hence worn out romance
Because Andante has been obsessed with hyoseop to the max, shin guy got curious and after he find out hyoseop is ss guide, he keeps trying to chase him and get him away from Andante. Not saying Andante is good, but i believe Esper are always self centered.
Can't believe i saw ppl said it's boring and frustrated, but oh well, we can never satisfied everyone and of course everyone float on a different boat
