Sana's been cheating on Tzuyu. Tzuyu knew it but still decided to keep loving Sana. But once she was slapped with the reality, she chose to let go. She let go once Sana was willing to hold on. "I'm just so happy right now. We've been through a lot. We've been hurt enough. We've shed painful tears so much. But now we're here, we're so happily in love." Sana softly chuckled as she leaned in Tzuyu's touch, feeling the warmth that the younger's touch is giving. "I guess those mistakes and regrets brought us into this. Those mistakes taught us to be strong and those regrets served as the reason for us to hold on" Tzuyu looked at the love of her life so lovingly as she says.
