Janu visits the garden, where he encounters Oki tending to tea for three elderly women. As they converse, Oki requests that Janu address her as "Sensei" to maintain decorum due to the presence of her aunt, who Oki identifies as a "spy." Despite Janu's persistent attempts to convince her to use his first name, Oki remains cautious, noting that she is not yet ready to be that informal.
The two discuss their connection, with Oki teasingly mentioning a "rebellion" among the girls at school. Their interaction turns reflective as they discuss the garden's atmosphere and the nature of their relationship. Oki eventually reveals that she is not capable of feeling anger, only sadness, which helps explain her calm demeanor. When the elderly women eventually scold them for talking too long, Janu attempts to intervene by claiming his authority as her teacher, which only shifts the women’s ire toward him. The event concludes with a slight increase in their bond as Janu leaves, reflecting on his growing connection with Oki.
