That morning, Dela has a run in with Shiori and falls in love with her. After Dela ends up getting lost, Shiori escorts her back to Tamako’s house, where Tamako attempts to become friends with her. Due to coincidental situations with her family, Shiori soon ends up staying for dinner and joining Tamako to the baths. The next day, Shiori tries to work up the courage to thank Tamako for the other day, but has difficulties overcoming her shyness. As Shiori ends up helping her homeroom teacher to Tamako’s house for a home visit, Tamako takes her to a coffee shop, where she is finally able to convey her feelings of gratitude. As the two become proper friends, Shiori gives her thanks to Dela for helping her out, though rejects his proposal of love. Afterwards, Tamako hears from Midori about how much courage it took for her to convey her feelings properly.
