The couple shared a proposal video on their YouTube channel.
However, Chikako and Taishi both posted on their personal Instagram accounts on Aug. 1 that they are no longer together.
Chikako wrote in Japanese and English:
“To my wonderful Terrace house friends –
Some of you may have noticed that Taishi and I have not been making appearances together. I would like to share that Taishi and I decided to go our separate ways a few months ago. We decided to keep this news private to give both of us time to move forward.
Taishi and I are still as close as we were. We will always be best of friends.
Thanks to everyone who supported our relationship. I will never forget how you took time from your lives to send kind messages over this past year- I have genuinely appreciated the incredible support and love we have received.
Thank you again, and I cannot express how much I appreciate your support.”
