The bpd label is a bit too easy to slap onto people, she just seems very insecure and anxious, so she needs to be constantly reassured, not healthy but not really bpdMizuki is clearly BPD or something similar but that doesn't give Ren any right to treat her this way... she should just be honest and breaks things off instead of developing the relationship further while actively lying to her
Wait did we already have confirmation that Mizuki is Sui's crush?Ren... Honey I know that it can be tough to set boundaries, especially when you kind of like the girl.
But lying about it is only going to make it worse!!!
Also frankly Mizuki, clingy and toxic as she is deserves someone better who won't send those trust issues she has stratospheric
What happens when Ren finds out that Mizuki is clearly Sui's crush?
