you broke up with your boyfriend and that was a long time ago and it doesn't affect you anymore but Riki only found about it now from someone

you were cutting onions because your mother told you to and it was hurting your eyes which made you tear up, Riki's close with your mother so he could just barge in anytime he want and saw you in the kitchen, tearing up but doesn't know it was just the onions so he quickly approached you and made you turn to him and asked, "why are you crying? is it because of that jerk?"
