I completely agree. The problem with kids like Kokonoe (and to be honest, most teenagers are still way more like kids than like adults) is that they mainly look at what's directly in front of them, and they feel their emotions at 150% intensity. Sensei has to be the adult in this situation because he IS the only adult in the situation. It's immature to equate being responsible with being mean. If kitty wants to be in a real lasting relationship with an adult, he has to learn to think about things more responsibly and practically, from the sounds of it (even though he's adorable and I feel sorry for him).
i feel like sensei is behaving right. kokone most likely chose a job that would bring them near each other. but sense's job sends him everywhere. reading all these different series, we have seen it already. He doesn't want to influence his future like that. part of being a good partner sometimes, is taking the harder path.
