The supporting character's harem is very normal - Chapter 28: This is…

[R18 novel with a lot of sexual content]Artem never expected to take on the role of a villain, let alone transmigrate between harem novels. Bound by a system, his task is clear: steal the heroines from all the protagonists’. From Chinese Cultivation and Korean Gate to Japanese Isekai Fantasy, VRMMORPG, and beyond—no heroine is off-limits, and no protagonist is safe!

After her mother’s passing, Tabitha Collins’s father marries a new wife and sends Tabitha Collins to live with a family she barely knows. There, she meets Alexander Foster, the family’s high-flying Eldest Young Master, who wants nothing to do with her. Apart from him, however, the other members of the family loves her and dotes on her. Soon, things began to change. Alexander Foster becomes intrigued by the mysterious and seemingly untamable Tabitha Collins. Who is she exactly? Initially, the girl seems to lack confidence and needs protecting, but as he finds out more about her, he realizes, he's the one with the catching up to do!

After all the effort of climbing from a mere daughter of a concubine to the Crown Prince’s consort, before the veil was even lifted, I had become a “flower vase” actress!

Su Shen: “What? Acting?”

The people in the entertainment industry discovered something strange. The “flower vase” girl with the terrible acting suddenly improved! She was also proficient in all of the four arts (zither, Go, calligraphy, painting)!???

Host: Miss Su, there have been rumours that Film Emperor Xie refused to act in this drama because your acting skills are not up to par. Do these rumours reflect your real-life relationship with him? Do you two not get along?

Su Shen: These rumours are all groundless, made up by netizens. He is a very good senior of mine and has given me many suggestions to improve on my acting. We do get along (smile).

Host: Then let’s contact Xie Yan on site.

The phone connected with a “beep”, and a lazy male voice suddenly came through, “When are you coming home, I’m hungry.”

Host: ???!!!

Audience: !!!!!!!!

Su Shen: ╮（╯＿╰）╭
