They definitely meant platonic, but we've seen hints of Clara having romantic love for at least Iruma. So curious exactly what her feelings are. I'll say, I'd definitely like it better if the massive love between friends stays love between friends. In many ways I think friends can have better chemistry than lovers. Then for Iruma Ameri is the only romantic conclusion.
Nice end to the arc. Despite the trouble it seems to have been good for them just talking everything out and getting closer. Being more honest with their feelings. Really those pills should be mass produced for therapy sessions. Force someone to reveal what's weighing them down and air it out. Pure genius.
