What I found the most interesting is that there are essentially 2 main couples. I had originally thought the past cpl would just be simple flashbacks, but the series actually shows the development of their whole relationship, and it was so endearing yet incredibly sad at the same time. I was crying buckets all the time for them.

The main couple is just adorable, who doesn't love an ML who's loyal and graceful only to his bf, and MC who's just the cutest with the most adorable smile in the world!! I love the similarities between the past and current couple, the mirrors and links were executed perfectly. ML was the one being chased in the past life, but this time he was the one chasing MC, MC can be shy at times but also brave as a lion when he wants to. The cause-and-effects were done perfectly, especially the last episode really made me cry my heart out.

The overwhelming feeling whenever they remember their past lives, was really vivid, and I applaud the actors for their amazing performances. And sibling love really does transcend even time, the grandma scenes made me super emotional!! And I especially like how the parents aren't the typical antagonists (both the current and past life ones), we see how the past parents had actually loved their children, they didn't want this tragedy to happen.

Truly one of the most spectacular written BL series, there's the perfect amount of romance, that doesn't need to be shown through explicit scenes.
