The moment when Yunho heard all the conversation, his heart already crushed.

It was not only because BoA had to leave the company for them. It was his first time knowing BoA had dated in the past and it was with his best friend. He still remember how BoA tried to cheer him up despite her having the hardest time.

At the door

BoA: hey, what are you doing here ?

Yunho: i came to see if your alright...

BoA: oh thanks, im fine ur already heard everything no ?

Yunho: yes, sorry i didnt want to bother you

BoA: its fine

While walking in the corridor, Yunho wanted to change the awkward atmosphere, he then straight up and ask BoA:

Yunho: why didnt you tell me ?

Boa: tell you what ?

Yunho: about him ? That you guys were dating..

At that point, boa was smilling a bit: are you jealous now ? trying to bring down the serious atmosphere

Yunho: im serious, you should have tell me. You were having the hardest time and you didnt even tell me... Knowing this, me and changmin will have take cared of you and not the other way around...

Boa: dont worry, i was okay and i dont even know if it was dating or not...maybe we were just close ? But everything shattered after that, i didnt get to see him anymore so ive moved on, just like the two of you

At this point, yunho knows that he hurt BoA, she didnt want to think back but he was the one bringing back all those memories

To lighting their situation, yunho then suddently change the subject

Yunho: hey what are you doing now ? The boys are at the house. Come with me, we will met up with them

Boa: ah nah its okay, im kinda tired i want to go home and rest you guys have your guys time

Yunho knows that she must tired to handle all this but he didnt want to leave her alone. After all the convincing, yunho still didnt get boa to go with him and he left sm. Afterall, she was still boa, noyone could talk over her

It was past 3 oclock, boa was still in the office, more precisely in the training room. She still remember the time when there were 6 of them then it became 3 of them and then now she really left alone...
