If you're looking for a logo that is cute and heartwarming, I would recommend a design that features a character holding a heart in negative space.
This type of logo can be used for a variety of businesses or organizations, such as charities, gift shops, or even personal blogs. The character holding the heart will create an emotional connection with your audience, and the use of negative space adds an element of creativity and uniqueness to the design.
You will get a document showing the rights released from me, also the vector and image files.
Additionally, there are some brand designers who are interested in designing logos to specifically sell them in logo design marketplaces like here.
If you want to purchase a logo from a designer and don't want it to be present even on inspirational design sites after purchase, make sure to request this from them once you've purchased it.
