When someone tells me that "you must come!" It usually makes me not want to go.
Instead of wanting to go more, when someone tries to force me to go somewhere, I 'll not want to go.
When someone tells me that "you must come!"「誰かに{行かなきゃいけない}って言われたら」 It usually makes me not want to go.「行きたくなくなるんですよ」
Instead of wanting to go more,「行きたくなる気持ちと正反対に」 when someone tries to force me to go somewhere,「人に行かせられるときに」I 'll not want to go.「行きたくならない」
