Shaurya was resting while Akansha kept waiting for him to wake up. Every moment with him kept running in her head like a reel. He was the gentlest with her, he always took care of her, if she eliminated a few situations where he had hurt her, the first and foremost being the moment when she got to know through Aakriti how he pulled an act of being in love with her which was a lie but still it hurt because his intentions were different with her. The second being when he said she deserved the betrayal she got. The third being the time when he threatened her to marry him. These are the three most painful moments Shaurya gave her. If she eliminated this, she barely found him speaking harshly to her or with an intention to hurt her. He loved her from the day he saw her, much before the issue with Aakriti happened. So he already developed feelings for her when he approached to deceive her, she wasn't defending his act but trying to acknowledge the facts that could balm her wounded heart.
