Caspar was still trying to call Finland as he looked for her on the 20th floor. His phone calls were not picked up, but Caspar was not worried at all. His heart was still overflowing with happiness because he finally received what he had always been craving for: Finland being jealous and irrational.
He remembered that it was very difficult to open Finland's heart to love, and even after they were together, he still felt that the girl was protecting her feelings from him.
Only once had Finland shown jealousy at him, and that was when he had teased her using Famke. At that time, Finland was furious because Caspar seemed to deliberately want to make her cry, and since then Caspar had never repeated his actions.
After that, Finland returned to being an aloof person who was not expressive with her feelings, especially after they separated for years.
