I was never really a fan of April but I did get my attention from hyunjoo since debut and I paid attention to her. Somin's departure was strange to me at the time but I didn't pay attention to it.
Hyunjoo's departure was much weirder, she was the center and one of the most popular members, why did she leave? That did not suit her and it did not suit the company. The company (and she) said it was for health problems and to dedicate herself to acting but months later she participated in The Uni.t, where is the logic?
Her departure was at the end of 2016 and The Uni.t in 2017 .... She left her group to participate in The uni.t being under the same agency when she could take a long hiatus and come back?
It doesn't make sense and it's very weird ... It sounds more like an outing due to problems in the group, this does not mean that she was really abused but there is definitely something strange.
