For me it is the beautiful art, manhuas have the advantage that they are coloured in the first place but also alone all the designs of the outfits they wear are fascinating, for me at least xD. Also it has the right amount of humour (every time with the chibis) two very great mcs with a realistic story, when we set the time travel apart^^ the ways and time it needs to fix that broken relationship is imo very well done for them both, also drama from other parties aren't dragged out for eternity, so the main focus stays where it belongs.
Love it that someone (probably A'Xiu) has put a glass dome around the cactus that a certain someone doesn't hurt her precious fingers again^^ Just give her something else to play with when she can keep her hands still xD
