Alexa's request shocks Helena. Her concern is understandable because her situation is really bad, but imposing that as a condition for the alliance with Lucien leaves her with no option.
Helena thinks about explaining how her heart is broken, and she doesn't want to be romantically involved with Lucien, risking suffering more in the future. However, the determined expression of her granddaughter makes it clear that she will not give up on that idea.
[I don't need to fall in love with him... it should just be a few nights...] She thinks while looking into Alexa's eyes, who is still lying on Lucien's lap, which makes that situation more embarrassing.
"Grandma?" Alexa asks while Lucien also makes a curious expression.
"I... I..." Helena starts to stutter as her face blushes even more. "I accept. I'll let him help me... But I need some time to prepare myself."
If you want to help LK grow, using your power stones in my other novel (Becoming the God of Love), is the best way.
