From Beginning to the End (Jeongcheol)

What happened?

3rd person pov

Seventeen was preparing for their performance stage. Mingyu, Wonwoo and Seungcheol had gone to the toilet while the rest were in the waiting room.

'Jeonghan-ah! Can you go find them? Seungcheol isn't answering his phone'

Jeonghan stood up, dialling Seungcheol's number and ran out of the room, in search of his boyfriend and the other 2 members.

'Wonwoo! There you are! Manager-nim is looking for you. Where are Seungcheol and Mingyu?'
'They didn't go back? They left the washroom before me though'
'Oh thanks. Just head back first'

Jeonghan panicked, fearing something had happened to them. He had called Seungcheol many times and each time, his phone was sent to voicemail. Seungcheol never ignored his calls.

'Mmm~ Fe~els so good! So tight!'

Jeonghan sighed when he heard moans coming from the room near the washroom. He knew what he was expecting when he opened the door. The sight of Mingyu dicking in and out of Nayeon.

Knocking on the door before pushing it open, Jeonghan was prepared to just walk in with his RBF and chase Mingyu out.

'Mingyu! Manager-nim is looking- Cheol?'

Little did he expect was for Mingyu to be dicking in and out of Seungcheol. No one else was in the room. Seungcheol was bent over on the table, Mingyu pushing into Seungcheol, one hand grabbing and tugging Seungcheol's hair, another hand on Seungcheol's waist, both cheeks flushed red and sweating dripping down.

'F***! Jeonghan hyung!' Mingyu exclaimed, pulling out of Seungcheol, and putting on his pants quickly.

Upon hearing Jeonghan's name, Seungcheol turned to Jeonghan, panic flashing across his face. He pulled up his pants hurriedly, muttering swear words occasionally.

'Jeonghan hyung... mianhaeyo... I... We...'
'Just leave. I will talk to Seungcheol first.'

Mingyu turned towards the door and dashed out, not wanting to piss Jeonghan off any further, but not before flashing Seungcheol an apologetic look.
Hearing the door click, Jeonghan approached Seungcheol.

'Baby...'
'DON'T YOU DARE BABY ME, SEUNGCHEOL!'

Shouting the name Jeonghan only called Seungcheol when he was mad, Seungcheol knew this was going to end badly. He didn't know how else to explain the situation to Jeonghan since it was exactly how Jeonghan saw it. No amount of excuses or reasoning would ease Jeonghan's anger.

Jeonghan pushed Seungcheol against the wall and started attacking Seungcheol's neck.
