i'm finally get away from tsundere childhood friend, now what? Yandere stalker
by the way, my preference is depend on how "Yandere" the girl is.
for example, i would NEVER choose Gasai Yuno over Tsundere(e.g Kousaka Kirino or Kirisaki Chitoge), but i like Mikasa Ackerman.(though i barely watch/read AoT)
