Summary
They clear their throat, smiling and fixing their clothes in a way you’ve discovered means that they’re nervous. They clear their throat again, pulling out the anatomy book and flipping to a specific page. You catch Female Reproductive System and then they’re flipping the paper and, yep, that is a full-page illustration of a vagina.
You…don’t quite follow.
“I have realized,” Chara says with a strained smile and note of hysteria, “That I have absolutely no idea what I’m doing due to the fact that I have been dead for the past hundred and ten years and never had to go through female puberty!”
Ah.
...
Becoming your own person after ten years of body sharing makes for some growing pains. Frisk is there to lend a helping hand. Or mouth. Whichever works.

Summary
Chara needs to get out of the house, it's just too sad to see Toriel like this, after everything that has happened. Thankfully Chara has access to a car now, Toriel can get mad at them for leaving with it without permission later.
Frisk is working in the middle of a weekday, again. The only person in the shop, again. Dying of loneliness it's so sad man.... if only a cool and handsome young adult maybe possibly named Chara Dreemurr could save them from this hell, maybe Frisk could do the same back. -

After fleeing from your Coven, you try desperately to protect those you love from its members, but what good are you as a Healer lacking the ability to use magic attacks at will?

Summary
When Asriel Dreemurr attends a rock concert the day before starting at his new high school, he had no idea that his life was about to change. There, he meets Chara, a wild and willful human who will show him sides of the world that he never could have imagined. Together, Asriel and Chara will discover that living is more than just existing, that love can be both happiness and pain in equal measure, and that as long as they are breathing, there is still hope for something better.
And at the end of it all, sometimes, the best that we can do is ensure that if life is going to leave scars on us, they will be the scars that we choose to let it leave.

Summary
—Si quieres elegir uno está bien, si vas por una opción diferente también está bien, si eliges ambas está bien, y si todavía no estás listo para elegir algo eso también está bien. Es como cuando yo quiero elegir caramelo o canela ¡No puedo! Así que creo mis propias opciones.
—P-Pero… Ese es el problema ¡No es que esté eligiendo! No es lo que quiero, es lo que soy ¿Qué soy? No siento que sea una niña tampoco ¿Entonces qué soy? No tengo una tercera opción... No tengo un tercer camino.
