BamBam's popular YouTube series 'Bam House' is back with season 2, and its first guest is MAMAMOO's Hwa Sa!

On this episode, Hwa Sa was invited into BamBam's new home to try out BamBam's homemade papaya salad, and also try malatang for the first time. During introductions, BamBam pointed out, "Many people are wondering, do BamBam and Hwa Sa know each other? So let me tell you how we know each other. We used to be next door neighbors for 4 and a half years." 

BamBam then added on, "I have so many stories from those days to share, but I'm not sure how much of it I can share publicly." Hearing this, Hwa Sa said with laughter, "I'm okay with you revealing everything."

As BamBam began preparing the papaya salad, he asked Hwa Sa, "What kind of neighbor would you say I was?" Hwa Sa replied, "BamBam was a very warm neighbor. You have a very comfortable tone when you speak. It always felt nice to talk with you." 

BamBam then began recalling one of his encounters with Hwa Sa, saying, "I remember one time, it was a day when I was cleaning the house. I was wearing slippers, shorts, a sleeveless top... and I'm so twig-thin. I was carrying trash bags in my hands too. I was waiting in front of the elevator, and then the door opened with a 'Ding!'. Hwa Sa was there, in full makeup. As soon as I saw her, I said, 'I'm sorry'. Not 'Hello', I'm sorry. (Laughter)." 

Also laughing at BamBam's account of what happened, Hwa Sa told it from her side. "No, the way I remember it, you looked cool. Do you know what I thought at that time? I thought, 'BamBam looks fine even when he's not made up. What am I gonna do?'." 

That wasn't the end of BamBam and Hwa Sa's awkward encounters. BamBam began describing the next story, sharing, "One time, I ordered delivery food. I was going to pick it up from outside the door. As soon as I opened the door, [Hwa Sa] was there. She was also opening the door to pick up her delivery food. I said, 'Hello,' picked up the food, said, 'Enjoy your meal', and we both retreated back into our houses."

While Hwa Sa burst out laughing at the description of the encounter, BamBam continued, "To be honest, we both looked pretty bad at that time. After that, I was always careful when I opened the door. (Laughter)." 

Hwa Sa had her own accounts to share as well. She remarked, "I remember that if I saw delivery food at your door step, when I came out of the elevator, I always tried to go inside as quickly as possible."
