In "Marry My Husband", What Is the Most Upsetting Act Of Park MinYoung's "Friend" Song HaYoon?

Buying genuine items for herself and giving me imitation gifts to create a comparison.

Pretending to take care of me, pretending to be nice, but then swearing about me to other friends in my back.

Intentionally approaching and stealing from me my crush or people who likes/liked me.

When she feels bad, intentionally attacking me to feel better.

Flirting and cheating with my lover.

Taking away all the things that look good to me.
