The protagonist of "Khem Sorn Plai" is Cherd, a stunning woman who is constrained to live abroad in Dr. Ruengboon's marriage. She discovers herself falling in love with Lanna, a Thai student studying abroad, while stuck in a loveless marriage. Cherd is compelled to remain married to Dr. Ruengboon since he won't grant him a divorce, nevertheless.

Eventually, Lanna makes his way back to Thailand where he starts a new life by weding Yaowayod, a young lady who is ideal in terms of both appearance and social standing and who was most importantly picked out for him by his mother. Lanna, who is married to a lovely woman, can't help but think of Cherd often and keeps her in his thoughts covertly.

Cherd is also ultimately divorced by Dr. Ruengboon after he learns that Lanna has wed, allowing her to return to Thailand and start over. She still maintains a lit candle for Lanna, reluctant to let him go, despite the several young men who are eager to examine her. What about Lanna, who claims to want to reunite with Cherd once more but doesn't want to leave Yaowayod?

The manifestation of young people's passions and Cherd's decision to be free of the debt of the term "love" are the story's secret threads. Cherd spent a long time being misled.
