The more Setsura thought about it, the more bothered and irritated she got. Akito did not tell her any of this. If she did not accidentally find out, would he have kept it from her? No Akito is different; this is just her petty jealousy. Such ugly and unwanted feelings, when was the last time she felt such things?
Jealousy is a beast in disguise.
Setsura recalled telling that to her friend, who worried about her boyfriend cheating. This was the same friend who told her to treasure her first time. Before they had that conversation and before she knew what happened. Setsura gave her that advice. Acting on your emotions will do nobody any good.
If you suspect your partner having an affair, you confront them calmly. You don't hide it.
After giving that advice, Setsura didn't hear about the matter for a long time. The next time they brought up the topic of love was that talk on first time. Judging from her friend's tone, all the unease vanished.
