Ah... Her name is Amane (from Fruit of Grisaia). She is very lovely! By making her a lover, it's to become happy!

0.6-0.8 weight produces pretty good results. Okayish at mixing with other Loras and checkpoints, I put some of my favorites in for reference.

I "upscaled" all preview pictures 1:1 with R-ESRGAN 4x+ Anime6B in order to get a more defined, lineart-ey look.

She tends to put her hands on/behind her head, if you do not want her to, try putting "hand on head, hand on own head" in the negative prompt or add poses to the positive prompt.

Not 100% happy with this yet, might remake it at some point.
