Due to her extreme embarrassment Rayzel's heart skipped a bit at what she said and without hesitation, she moved swiftly as she covered Mika's mouth with her own hand,
"Mikaaaa! Tone down your voice…Aling Martha and the other maids… might hear you!" She almost choked out those words without looking at her as her eyes were glancing towards their surroundings.
This is why Rayzel doesn't want to talk to Mika about this kind of thing if not in private as she is completely aware of how loud her best friend could get when she's excited about something.
Mika couldn't help it but the corner of her lips lifted upward under the covering hand of Rayzel. She was too overwhelmed to act normally. She stared into Rayzel with teasing eyes
"Oh my goodness! Confirmed! OMG! OMG!" Mika clapped her hand in the air while Rayzel covered her own face in utter embarrassment.
