That aside, Mu Liang didn't find anything offending. When Mu Feng was wiping Mu Lan's mouth, Mu Liang took it as elder brother caring for his young her sister. There was nothing wrong with it. Moreover, Mu Liang was relaxed seeing that Mu Lan was having meal.
Mu Feng always wanted a younger sister and he was used to say, "If I have a baby sister, I will spoil her like a princess." His dreams came true after Mu Lan came to their house. He was also guilty for harming her two years ago, so his attitude towards her was also better.
Aside those things, Mu Liang was thrilled when he saw the pictures of Mu Lan going to the lingerie store. He kept waiting till night how she was going to entice him. He was also prepared that no matter what she did, he wouldn't fall in the trap. But everything turned upside down after he saw her in the last night.
He really underestimated his opponent and miscalculated the depth of his love for her.
