He crushed his car into the lake on purpose or not. No one can say for sure. I think his family told him that Hakyung is died after the accident. He didn't believe it but Hakyung didn't come for him so he's kind of losing hope.
That's why his older brother reacted fiercely when he saw Hakyung. They don't want they meet again, afraid that Yoonsung will risk his life for Hakyung again. Well, Korea is still very homophobia and they're a high-profile family.
