9/10 - frustration > angst

Title: One Night One Day One Year One Lifetime (CN)
[COMPLETED]

FL's obsession over ML and how she forced him into marriage made him loathe her. He treated her worse than a piece of trash. But he only realises his feelings when FL got diagnosed with terminal cancer... but he keeps denying his own feelings until it was too late.

9/10 - What they both need is therapy. Thats what they need. Goddammit.

FL was a daughter of corrupted noble family. ML went undercover in their house as FL's butler so he can uproot the family's regime. FL and ML fell in love while ML was still undercover. Then time came, when she realised the ML she knew was all a facade. Did he even love her? Or was that love fake too, like everything she knew about him? She was beheaded along with her family, then reborn.

7/10 I actually cried with this manga.

*Transmigrated* FL and ML (emperor) married under a condition that FL expects no love from the marriage. ML slowly starts finding FL interesting, but figured FL has been neglected for so long she doesn't expect anything from him. Regrets start rolling about how he treated her. (This phase only lasts for the first few chaps tho, so the overall angst is not too great)

4/10

Title: Our Second Master (CN)
[COMPLETED]

Novel about a frivolous second master (ML) who only knew how to run amok with his pretty maids, and the only "ugly" maid servant (FL) in his manor who always held the brunt of his abuse. Tables turned his whole family went bankrupt and he got disabled. All his servants ran away while the ugly maid stayed beside him despite the troubles... but she wants to leave him once he gets better.

9/10 - short story

Typical "can't communicate but I love my wife" ML misunderstood by the FL, FL with post-partum depression who was trying to escape from her parenting responsibilities. Then FL got a terminal disease and realised she never spent time with her son.

Time rewinds and she decided to give all to her son, but her son is uncomfortable with the sudden change in his mother's behaviour. He keeps treating her wrong... then regrets when he learns of her illness

4/10

FL suffers under her husband and twin sister's schemes. Technically, the husband doesn't regret what he did (actually he doesn't even think he did anything wrong, that's the kinda asshole we're dealing with). Instead, FL got her revenge, trash suffered from her retaliation and went crazy.

So this aint for ppl who came for ML's tears, it just had similar premise of *abused FL got enough*.

3/10. Might remove from the list later
