背景时间是1963年。以47年前的横滨为舞台。那是一个因人口过于稠密而开始呼吁控制人口的时代，主人公们则是比这个时代稍早的高中生们。那时还没有出现首都高速路，被称为交通地狱的街道上也堵满了电车。作为家族女眷中长女的主人公海是一名高中二年级生，因父亲在海上下落不明而帮助母亲打理包括寄宿人在内的六人大家庭。然而有一天，因卷入新闻部长与学生会长之间的风波，她平静的生活因此被打破了。In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).独立干练的女白领何大叶被扣上了“大龄剩女”的帽子，尽管面临催婚压力，但是她依旧没把婚姻当“人生大事”看待。她选择追求事业上的成功，认为女人靠自己比倚靠婚姻和男人更靠谱。其实，三年前何大叶曾与飞行员男友罗畅牵手走过婚礼红毯，不料婚礼上罗畅却突然拉着大叶一起逃婚，事后罗畅坦言自己没有做好结婚和承担责任的准备。大叶原谅了他，两人和平分手。离婚后的何大叶，与前夫保持友好往来，生活中互相照应，尽管都对彼此心存幻想，但始终没有更近一步。后来，大叶与过气男模张猛不打不相识，尽管张猛遭遇事业和生活的瓶颈，但是他有责任有担当安全感爆棚，感受到爱意的何大叶既享受又纠结。最终，在张猛的理解和爱护下，大叶卸下防备，坦然面对这份感情，两人走到了一起。不是天启小说改编，是原创故事。现在越国境内可以说是遍地良田。与此同时，同时彭城以北数百里，一条宽阔清澈的河流缓缓流淌。85.5/74.9-1=14%
