No, really, this can't have meant anything to Isechi. She was just in a breakdown from being turned down by Kaoru and rebounded when she could get her hopes back up. Looks like Kaoru likes her back even. The only drama this could possibly start is Saitou's solo "if I can't have her no one can" drama. I mean that or this becomes another series I stop reading till it's finished looking at you, Citrus.
