Chances are close to 0:
- Red hair = Pretty rare, about 5% of the population
- Blue eyes... Well, that's not too hard since most red-haired people also seem to have blue eyes
- 14 year-old: well, that's certainly possible
- Graduated from a german university: Close to impossible. Your average German student graduates at age 23-24, even with the new Bachelor Degrees (Graduating at about age 21) you'd have to skip 7 years in order to reach this.
- Tsundere? fucking impossible, since the whole tsundere archetype exists to please social rejects ("All the girls who despise you in public? They secretly love you.")
