After We Broke Up, I Found Out My Boyfriend Was a Walking Red Flag

[Synopsis screenshot archived on June 1, 2025]

Before they broke up, the heroine thought her boyfriend was wonderful in every way, just too emotionally distant. She couldn't understand why he was dating her.

She was straightforward about it: if the relationship made her unhappy, she would end it. Her boyfriend was surprised, but they parted politely and amicably. Neither of them ever spoke ill of the other in public. Their friends thought the breakup had been very dignified and began introducing her to new people.

Even when she awkwardly ran into her ex at a blind date, he offered her his sincere best wishes.

“My ex really is a good guy. It's a shame we weren't right for each other.”

That was what the heroine always thought, until she found her boyfriend's secret account:

[Why did we break up? I knew that bitch was seducing you. You flirt with everyone, flirt with everyone, flirt with everyone, flirt with everyone. You're always like this. I'm sorry I couldn't give you the best. Why did we have to split up? Can we get back together? Get back together, get back together, get back together, get back together.]

[She smiled at someone else. That bitch. I'll kill him.]

[I hate you, I hate you, I hate you, I hate you, I hate you, I hate you. Why did you break up with me? I hate you, I hate you. I love you. I'm so worried about you. Can you forgive me?]

[Why can't you look only at me? I'll lock you up. Who else could love you like I do?]

The heroine: ...?

Was that guy before just cosplay?

#The truly dark and unhinged ones always show up looking like perfect wives and mothers#

A handsome, polished, and seemingly unruffled possessive boyfriend who's actually easy to break down x a steady, honest partner who attracts admirers (with a built-in succubus buff that makes the boyfriend lose it every day)

The boyfriend loves taking care of her. He gets so carried away doting on the heroine that he could die happy. He's great at housework and pretty much everything else, too.

Content warnings:

1. The boyfriend's mental state is extremely unstable. No stage has even been set, but he's already itching to put on a show. He makes a scene over everything and thinks every man he sees is a fox spirit trying to seduce the heroine. He attacks everyone indiscriminately and is completely deranged. He makes snide remarks about all men but never insults the heroine.

2. Aside from his personality, the boyfriend is top-tier in every way, and his love for the heroine is no exception. You can question whether he's really 189 cm tall, but don't question his feelings for her, or he'll have a massive breakdown and go rant on his secret account.

3. The heroine loves the boyfriend too. Their feelings are mutual.

Theme: Love needs good communication.
