That ex-boyfriend of her is really ungrateful and a jerk! The least you could do for someone who you have been dating for 7 whole years is not badmouth them, just end it on good terms.. that's sad.
Also, the singer.. he seems like a sweet guy I feel sorry for him, though some relationships are just not meant to be, hope he finds someone great.
As for the FL.. I feel like she's lost or Idk, she seems to be going with the flow I hope she finds a more clear picture of her future.
Team leader, he's so adorable I support their relationship strongly, though I like their current one as friends/coworkers.
Thank you so much for translating this, really appreciate it!! <3
