Overall, An En feels he still prefers Dang Yang and An Yue being together.
At first, when he learned Dang Yang harbored inappropriate feelings for An Yue, he was indeed upset, thinking their age difference made them unsuitable. But gradually, he realized that sister-brother romances are becoming more common in society, and those can be very happy together.
Actually, whether a man and woman can be happy together isn't majorly related to age.
Men's maturity isn't strongly linked to age either. Some young guys are mature and sensible by their teens, while others are still selfish, cowardly mama's boys even at thirty or forty.
Initially, he cared about age difference, but lately, he's been letting go of this concern and truly feels Dang Yang and his sister are quite compatible, and they'd be happy together.
Of course, he wouldn't pressure his sister or impose his thoughts on her, but... for her happiness, he'd create opportunities for Dang Yang to charm her.
An Yue: "..."
