BaoBao has not yet informed Naoko of everything that went down in the gym.
Because BaoBao has already grown used to the negative thoughts that Naoko no longer avoided, the eerie silence he was met with now spooked him into not daring to make a sound. The silence in her mind now was worse than when she thought of nothing else but work in their first three worlds together.
Naoko's face was slightly scrunched up she was trying hard to hold something back. She had punched the wall hard upon entering her room. Her chest heaved despite her attempts to take deep and slow breaths. She leaned against the wall, slowly slid down onto the floor, then buried her head into her crossed arms on her bent knees.
A while later, sound of the door sliding open could be heard but Naoko kept her head down.
Tadashi looked sadly at her small figure slumped against the wall. He let out a small sigh and said softly as if to inform her of his presence, "I knew you'd be here."
