Tsundere Tag, Yandere Tag...google...Dual personality? I'm not sure about these tags.
Edit:
Berry = MC's Milf Teacher
Sarena, Berry's oldest daughter (and she has a girlfriend)
Emma, Berry's little daughter
Valerie = the girlfriend of the MC's father ... Stepmother
Possibly "stepcest". With stepmother. And stepcest is also tagged here as incest.
And after a blowjob, you can redefine relationships and define Berry as a mother ... Berry's daughters you can call old / little sister.
Or Aunt and cousins. Each player chooses what they prefer. But Emma refers to the MC as a cousin when talking on the phone to someone else.
