Yeah that's true lol, but she still has this sense of obligation to carry out her duties is what I feel from her, but even if she gets out quick, I think a successful solo modelling/acting career is just lying in wait for her in Japan and she'd definitely prefer it over IZ*ONE but anything could happen.
It's definitely possible she could prefer a solo career in Japan over IZ*ONE, but if the extension was for 2 years for example or smth like that, not quite a full usual kpop contract length.... She might just go for it tbh. A thing I really wanna note, is that Sakura has really gone in on improving herself in Korea, even more than Nako and Hii-chan I would say. She has been concentrating on dancing and singing lessons a LOT, which does KINDA indicate to me that she wishes to continue doing SOMETHING idol-ish y'know
Tbh I dunno if Sakura has that feeling of obligation for the 48g any more. Basically all other big names who you would think would also be obligated have jumped ship. Not to mention her ranking no.3 in the 2018 sousenkyo really hit her hard.
it's hard to tell WHAT exactly she wants due to her really being a pro idol. We don't know whether she would like to be in IZ*ONE, be in HKT48, be in both, be in none of them.... I have honestly no clue.
