Passionate as in ruining his own position at the company and impulsively getting married to an alpha he barely knew
Selfish as in one-sidedly broke off their marriage
Selfless as in letting Taegeon go, fearing that his husband would be wasting his time if they were still together, or the fact that Jaeha might swallow him whole and kept Taegeon for himself, and Jaeha's jealousy grew so intense that he's scared that he might ruin Taegeon too

Jaeha, you're still the most passionate, selfish and selfless person in love and I will forever love you for that. What a heck of a beautiful character you are
