Bit harsh to hate on Good Guy Rintarou for acting like a decent human being who cares about his friends, I'd say. ¯\_(ツ)_/¯
It's always like this is this site, good guy --> "fake personality", "dumb ass", bad guy --> "Douche bag PoS", good girl --> "she's a wonderful person", bad girl --> "she just does things her won way":
people always say some crap like that, I wish yuri forums were less man-hating and more love accepting.
