Honestly, they didn't even need to do the whole back in the past storyline it looked like past Taehyuk felt forced to reciprocate Hyo-un's feelings and had his doubts as smn who was in a parent role to the dragon but present Taehyuk actually fell for Hyo-un of his own volition as an adult without the shackles of raising him beforehand and memories of the past influencing things and getting in their way in general. Smh I wish I didn't read the backstory, it nags at the back of my head when I'm reading now
