对于感兴趣的读者，欢迎反馈。
Once again, readers who are not interested or resentful of sexual contents can ignore this series to avoid unnecessary conflicts.
This series is for personal learning, appreciation and exchanges only, please don't upload any of its contents without my acknowledgments.
This series will not be translated into English version officially in order to maintain its context and emotions in certain parts. For interested readers, you can try to use translation software or model. (The major reason is the lack of my sexual proper noun storage, otherwise I will and even am enthusiastic to write the English version.)
This series will never be tagged with the original game 'hoshizoratetsudoutoshironotabi'.
For those who are interested, welcome feedback.
