I literally forgot that it’s her birthday today/tomorrow. Guess it’s a sign that I completely moved on from her departure! (But I explained this whole bit in the general discussion tab)
@vimoral Hello! I just had a look at Momoka san's tweet from October 13, 2018 that you were asking about...
I'm still struggling with the language, but this is my translation from Japanese to English:
"A year from tomorrow I'd like to be living a life where I don't feel ashamed of myself."
Without context it is very difficult to know what she might feel "ashamed" about. The hashtag you pointed out, #健康第一 means just that "Health First" as a priority, a way of living.
So maybe living a more relaxed life without stressful schedules she's enjoying too many delicious foods and not exercising enough. Maybe she wants to live more healthy and in one year she'll have changed herself. Just guessing though. It could also be that she has lingering feelings about how things might have ended with the band and she's struggling to get past it. But there is no context for that either.
She wrote a more lengthy bit on her Instagram page on the same day as the tweet talking mostly about being thankful to her fans and that she reads everyone's comments, the cold weather being similar to October the year before, and reminding people to keep warm. Didn't really see anything there that supports any particular reason she's feeling the way she is and her desire to feel differently in October 2019.
I had actually asked my Japanese friend but his English/German wasn't good enough to give a really good explanation And it seemed he wasn't too sure either
Ruthy's post is a very good guess I think after all those years and a childhood/adolesence spent in the limelight and doing things dictated by others Momoka was/is still in a state of finding out who she really is She seems to have a more holistic/ecological approach right now which does change your views on what you do/have done and your outlook on society and the nature of everything (and can tend to annoy others as those folks tend to become very preachy sometimes :) )
Looking at the larger picture it seems quite clear to me that she needed to get out or she would have lost herself
And finally we have the answers to her sudden graduation.
She tells it now because a reporter has caught them on the way home and it seems that it will be published in some magazine. Momoka apologizes if this information can annoy her fans.
