I just rewatched this and still love it! It's heart fluttering cute BL.

I learnt sth new about pacemaker and found the concept interesting. I also love how the ML actually trained his running skills due to his life situation. What a blessing in disguise

There are lots of cute little moment as well as touching moments. The sincerity of the ML really touches my heart , It's also inspiring to see the impact one person' life has on another, something that might be nothing for you may mean the world for others. It's deep and meaningful in its own way, although it's overall lighthearted and entertaining

Is there plothole? Yes
Is it perfect? No
Is it satisfying to watch? YES!

If you're just here for feel good BL, you're in right place
