a girl was born with the ability to see red lines and we follow her and several characters that are directly or somewhat involved with the red lines. it was honestly rlly intriguing. i was in slump of what to watch and this hooked me from start to finish. each episode just kept hooking and surprising me. i loved seeing the dynamics on different people and how they interacted and used the glasses. it took a weird,,? turn towards the end but i loved the watching experience nontheless. i hope we get season two >< such a fun watch. contemplated reading the webtoon ver. lolol 4.5 stars !
