Yes I agree. Her mishandling the situation this chapter has nothing to do with her voiced reason. She says she loves her girlfriend and volleyball and her best friend, but non of those things coalesce. It's never been about volleyball (e.g their anniversary, she could have easy made it both to practice and yuni but she forgets yuni, again at the festival, she convenient forgets she's asked yuni on a date and never once considered asking yuni if bringing her teammates was fine).
Namaste is fundamentally selfish (either she doesn't see yuni's struggle or she's elected to ignore it), which is funny because that word gets directed at yuni a lot, both narratively and by viewers.
