I think Lu may choose Zhao Donglai for the following reasons.
First of all, Lu's close relatives and people have always thought that it is not wood, and they will not know about it. However, Chen Hai took the initiative to introduce the object to Lu Yike, and he was obsessed with his dead wife. Can this relationship change overnight? Not falling in love with Lu, but feeling guilty and moved the most. If they get married, such a marriage may not be what Lu can aspire to. More suitable to be Lu's big brother. Xiao Qiu and Lu Yike are also a bit like sisters and brothers.
Secondly, Zhao Donglai is infatuated with Lu Yike and appreciates Lu Yike's persistence. Moreover, they have the same interests and talk very speculatively. Every time we are in the same box, we want them to be together for no reason. A humorous and affectionate, a vegetable lying in the hospital. Time is the best medicine to cure all feelings. I'm worried that in reality, Lu will probably come together with Zhao Donglai. In this realistic society, it is nothing for ordinary men to dare to climb the heights of the country. Everyone knows that love is free, but marriage should pay attention to the right match. Zhao Donglai and Chen Hai are both right matches for Lu Yike. People's hearts will be affected one day,
And Lu can also have obvious affection for Zhao Donglai, especially in this part of poetry.
In the end, Chen Hai didn't wake up in the novel. In the TV series, Chen Hai was adapted as Wake Up to make up for the sadness of Chen Lao's death. In this way, Lu can also be with Zhao Donglai without any psychological burden, and everyone is happy.
For a woman, happiness actually does not come from whether you are married or not, and who you marry. What seems to be a good match in the eyes of others is nothing more than secular comments. True love is not measured by matching or not, but by your heart. Whether you are happy with him or not has nothing to do with who you have been with. So being single is not necessarily unhappy, just like Lu Yike, who is really happy and lives freely.
