After Becoming a Widow, I Became the Twin Heirs' Beloved

[1V2 | Sweet on the outside, dark on the inside heroine | Love triangle showdown | Abstinent, aloof twin heir × unhinged, possessive general] Wen Wanyue was tricked by her stepmother and birth father into becoming a bride meant to bring good fortune to a dying man. Her bridal sedan had barely crossed the threshold, and the wedding ceremony had yet to begin, when he breathed his last. In an instant, Wen Wanyue became a widow before the wedding, cursed as a husband-killer and the biggest laughingstock in the city. The Yong'an Marquis's household had two twin sons, identical in appearance but polar opposites in temperament. Even more absurdly, she discovered that the sweetheart she had exchanged heartfelt letters with by flying geese was one of the two young masters of the marquis's household! Their letters were full of brazen, intimate words, with all their flirtatious whispers of love hidden between the lines. Wen Wanyue covered her mouth. Oh heavens, those scandalous love notes she wrote... Naturally, she assumed that the flirtatious, unruly, arrogant, and unhinged second young master, Xie Yunshu, was the secret lover she had been writing to! From then on, she cautiously flirted with him and tested the waters, showering the younger brother with tenderness at every turn. She avoided only his elder brother, Xie Yungui, a cold, abstinent man who was indifferent to romance and kept everyone at arm's length. Everyone in the capital knew he was the most untouchable flower on a high peak, a man who followed the rules, controlled himself, and shunned all matters of love. Only Xie Yungui knew that every one of those intimate letters, so full of seductive words and tender longing, had been written by him! The little rabbit who had mistaken him for someone else was now batting her eyes at his younger brother every day and giving him the cold shoulder. For the first time, a storm raged in his heart, and his restrained obsession began to grow unchecked. Meanwhile, the devil-may-care Xie Yunshu watched the soft, sweet little rabbit, sly beneath her gentle exterior, flirt with him every day. His carefree heart gradually began to fall for her.
