A single screen passing by twisted three years of a perfect marriage.

[Baby♡: Manager, last night was so good. Heart heart]

The message popped up on her husband Lee Sejin's phone. And in that moment, Sejin's ears turned bright red.

'...?'

The pride of Sunhwa Group's Strategic Planning Team, a couple with perfect visuals envied by the whole company. A couple still in their honeymoon phase three years into marriage.

Guest suppressed the rising sense of betrayal and regained her cold rationality. She had to catch the evidence first.

Someone who would call him 'Manager' and be called 'Baby♡'. A recent change in the team. There was only one answer. The Strategic Planning Team's rookie, Kim Sena. 24 years old, young, pretty, and quick-witted.

The next morning, Guest sent a chilling gaze toward Sena, who rushed into the office catching her breath. As soon as their eyes met, Sena looked restless, not knowing what to do.

'Right... it's you, isn't it?'

Just then, Guest's internal messenger blinked.

[Associate Kim Sena: Assistant Manager, I don't know if I should be telling you this...]

[Associate Kim Sena: Go to the 3rd-floor emergency stairwell right now! Manager Lee was... holding some woman there. T_T I'll pretend I didn't see anything.]

'What...?!'

It wasn't a confession. It was a tip-off. Guest silently rose from her seat and headed to the 3rd-floor stairwell. She slightly opened the steel door and peered through the gap.

Sejin was there. With eyes dripping with honey, he had his arm around a woman's waist, tenderly brushing her hair back and kissing the top of her head.

And the moment she saw the back of the woman in his arms, Guest's mind went completely blank.

A scrawny frame, gloomy clothes that didn't even fit, and unkempt, frizzy hair. It was Assistant Manager Kim Miyoung, Guest's colleague from the same hiring class, famous for being the most tight-lipped and plain person in the team.

'I'd rather... I'd rather you cheated with someone young and pretty like Sena...!'

Crash. The pride she thought was solid shattered into pieces on the floor. To think the person he cheated on her with was a woman like that. A terrible sense of shame and absurdity washed over her, even stronger than her anger. Even for a downgrade, this was hitting rock bottom.

Guest bit her lip and held up her phone. Through the lens recording the video, the ugly and ridiculous affair of her perfect husband was captured clearly.

After finishing the recording, Guest quietly left the stairwell. She walked up to Sena, who was waiting anxiously, and tapped her on the shoulder.

"Sena. Let's keep what you just saw a secret between the two of us."

"Yes, yes! Of course, Assistant Manager!"
