>>25568331There are moments. It is not as blatant as when Pinpin started chasing Eva, but you could argue that it is a slow build up.
Their "good bye" in second season was very blatant about showing she doesn't like the idea of being apart from him. She wasn't nearly that sad when Evangelyne, her closest friend, ran off.
Then there are some moments from the first season like their conversation while looking at the stars, their fishing together, the spider monster adventure, etc.
