Too Few Points, So This Cannon-Fodder Side Character Keeps Getting Everything for Free

[Transmigration + happy ending + lighthearted and upbeat + both leads are each other's only partner + groveling ex arc] [Goofy + strong-willed + loves getting things for free + cannon-fodder heroine x love-struck + narcissistic + obsessive + pure-hearted + villainous male lead] After transmigrating into the role of a cannon-fodder side character, Feng Yunyun discovers that whenever she's in danger, she can borrow a skill from the System in advance. Who knew the skill would be so amazing? The male antagonist, Huo Ling, starts hugging and cuddling her the moment they meet. Huo Ling clings to Feng Yunyun and says, “Yunyun, don't be afraid. I'll protect you.” Unfortunately, this wonderful skill only lasts half an hour each time. After that, Huo Ling turns back into his obsessive, twisted self. When she finally earns points, they either go toward paying off her old debts or get spent on making herself look gorgeous. From then on, Feng Yunyun starts using the System Store's free shopping feature, something she once looked down on but now can't live without. The obsessive Huo Ling insists on planting a love worm in Feng Xue'er, the heroine of the System's world, to make her fall in love with him. Feng Yunyun, meanwhile, has her eye on an ice cream maker and wants to earn some points. As the best “blood donor” for raising love worms, she has to rope herself, Huo Ling, the heroine Feng Xue'er, and the hero Huo Ran into going to Qingqiu in search of the worms, while completing the main quest and earning points along the way. But as the plot goes off track, Huo Ling's fantasies about Feng Xue'er fall apart. Then, after Feng Yunyun completes a quest and earns enough points to finally buy the ice cream maker she's been dreaming of in the System Store, she accidentally clicks on an exquisite bow right next to it. Huo Ling takes it as a token of her love for him. From then on, the great villain won't leave Feng Yunyun alone...
