Takopii no Genzai - Chapter 15

Okay so lemme get this straight, Takopii’s original mission was to make Marina happy to which he succeeded but later in life her life became miserable cause of Shizuka so Takopii went to his home planet to ask for his mother to turn back time to kill Shizuka to keep Marina happy but while doing so his memory was wiped

And now his entire existence was basically removed from the census to have the camera work once more and help Shizuka to be happy but with the unintended side effect of having her lose all the memories she’s made with the alien..

So answer me this. What the FUCK am I supposed to feel? Sad? Cause I’m only feeling confusion as to what the fuck’s going on.
