Both drama has parents-child relationship. "TW" is Korean Drama, and "IDWTBFWY" is Chinese drama. The similarity are both dramas are about the son/daughter go back time travelling to the past to meet their father/mother.

TW - son-father relationship.

IDWTBFWY - daughter-mother relationship.

I think a lot about to be similar, because the "TW" are still ongoing, so i cannot tell just yet. But, i really RECOMMEND y'all to watch both dramas. Really worth to watch.

Both series are fluffy and cute romance high school setting. It's really super sweet and cute chemistery between the male lead and female lead. When i watched 'When i fly towards you', immediately i thought about 'Our Secret'.

both FL in the dramas are younger than the ML, naughty, stubborn and strong.. ML in the MLSC is chief of forest or something like that, while ML in MY SECRET BRIDE is a lieutenant..

the FL in both drama are clever, independent, know all about forest.. they both are naughty and hard to listen to other people.. but, actually they have good intention to the nature and people..

Both drama take place at north thailand. So, both story has north thai music.. It is very addictive, fun to watch.. Both drama has handsome man lead and cute & pretty female lead.. And the best part is it's genre are comedy, bussiness, music, romance.. They are really similar just different in the story line.. It's worth to watch because you can take the moral of these two dramas..
