This manga's exploring the selfish side of attraction/romance, huh? Much less idealistic than the typical manga's view on yuri.
selfish yes, but it's also deceptive --- you can be selfish and transparent about needs, which Ren is not. She clearly responded to Mizuki's request to be her lover, but she keeps her side-job completely hidden. She's OK with meeting with Chitose because she views it as a job, but understands that Chitose's expectations are that these meet ups move into a relationship (even though it's booked from her job side of things), and doesn't explain to Chitose she has a girlfriend.
kinda want to see Ren eat the consequences of her actions with everyone lol
