Sana became rather quiet after Momo's death, and Tzuyu started worrying.
6AM in the morning, Tzuyu woke up to see the usual early bird's bed neatly made. It wasn't a surprise anymore, but Tzuyu couldn't shake off the feeling that something was off.
Silently, she made her way to the living room. She saw a shadow darting around in the kitchen and unhesitatingly, she walked towards the figure.
Tzuyu stood with her mouth agape as she watch Sana slip the missing kitchen knife back into its slot. Although it was confirmed that the weapon in crime was not the missing kitchen knife, Tzuyu still felt the uncanny feeling of this situation.
Her mind struggled. She wanted to find the culprit of Momo's death desperately, but...
...As she watch Sana lift the corner of her lips in triumph, she never stood up.
...As she watch Sana leave the kitchen, she hid and never acknowledged Sana on her presence.
...As the rest slowly rise from their sleep, she never told them.
In the end, she hid the secret for Sana.
