A mature sister with avoidant attachment in the upper year x A growth-oriented and economically independent sister in the lower year
There won't be any cross-border interactions during the school day. There will be sweets, but there won't be unrealistic large scales. It is also biased towards the younger sister growing up. The younger sister will become a guiding lover and be financially independent. She will move from a weak and helpless little girl to the bigger world. It will not be interrupted and will be updated all the time. It is a long story with entanglement and pulling. There are some hard-to-get tricks and delicate plots.
Intention: There is always someone in this world who is worthy of your steady love.
